When a WindowPreview is being destroyed, the class default handler for
the `destroy` signal is responsible for destroying its child actors.
This happens after the emission of the `destroy` signal, i.e. after
`WindowPreview::_onDestroy()` has been run.
The destruction of the WindowPreview's child actors now triggers a
re-pick, but due to WindowPreview having already being marked as
`CLUTTER_IN_DESTRUCTION`, it will not be picked, resulting in a `leave`
event if the cursor was on top of the WindowPreview at the time
`destroy()` was called on it.
So this leads to `WindowPreview::vfunc_leave_event()` being run after
`WindowPreview::_onDestroy()`, which means the idle started by the leave
event handler will not be removed and ends up accessing actors after
they have already been destroyed.

Dash labels are children of the main uiGroup and so could be destroyed
before their logical-owner DashItemContainer during shutdown.
This implies that we could destroy them twice. To avoid this, unset them
when destroyed.
This is mostly visible when using dash-to-dock, but it's still
technically possible with upstream code:
** Message: 19:57:49.847: Shutting down GNOME Shell
(gnome-shell:2788214): Gjs-CRITICAL **: 19:57:49.933: Object St.Label
(0x55b33668eab0), has been already disposed — impossible to access it.
This might be caused by the object having been destroyed from C code using
something such as destroy(), dispose(), or remove() vfuncs.

The left/right navigation between top bar buttons is usually
handled by a key-press handler on the button's menu.
However when a DummyMenu is used, the button itself serves as
fake menu actor and will get grabbed when "opening" the menu.
Due to that grab, the event is not propagated to the stage,
and regular keynav does not work.
To avoid the focus getting stuck in that case, add an explicit
key-press handler that bypasses the grab.

When the user clears all notifications from the notification menu UI, it's
possible for a queued notification to be destroyed after the currently displayed
notification. The removal of the currently displayed notification is not
processed until the notification menu is closed (due to `this._bannerBlocked`).
By then, it's possible that `_notificationRemoved` has already been overwritten
when `_onNotificationDestroy` is invoked with another (queued) notification.
This eventually results in a notification banner that cannot be removed by the
user as the notification object needed to do so has already been destroyed.
Fix this by only assigning to `_notificationRemoved` if `this._notification ==
notification`.

This is a small one time leak if there is more than one entry in the
search path due to multiple iterations overwriting the old pointer
before finally going out of scope.

When loading a symbolic SVG, the original file is wrapped in
a header that includes a generated stylesheet with the
appropriate colors, plus an overall opacity.
The opacity value is clamped to values between 0 and 1, which
directly matched the alpha field of the GdkRGBA type. However
since we moved to StIconColors/ClutterColor, the alpha field
is now in the range [0..255], any alpha value other than 0 now
results in full opacity.
To fix, translate the [0..255] integer into a [0..1] double
before using it as opacity.

Emitting this signal is broken right now: We check for a length of 0 on
this._objects[objectPath], but the
`this._objects[objectPath][interfaceName] = null` we do before the
check doesn't actually remove the key, it only sets the value to null,
leaving the key around and thus the amount of entries in the object doesn't
change.
Fix that by using the delete statement instead, "delete" properly removes
the key and thus affects the amount of entries in the object, making our
length === 0 check effective.

When checking for an extension schemadir, an error will be thrown if
`query_info()` is used and the directory is missing.
Catch the case of a missing directory, but throw an error if the
path exists as a non-directory type.

Both :icon-name and :gicon are propagated to the internal QuickToggle
with property bindings. However the bindings are set up in the wrong
order:
:icon-name is a convenience property to set :gicon to a ThemedIcon
of the given name. That means binding :icon-name first will correctly
set the underlying StIcon's :gicon, but then the :gicon binding will
set it again to null.
Fix this by swapping the order in which the bindings are set up,
so that it works for both properties.

Commit 9d75d777c7 introduced code to hide the subtitle of the
quick setting toggle when it matches the title of the toggle.
That's because NetworkManager tries to make the network names
more palatable on its own, and reports that the name of single
wired networks is "Wired" even if it may have another name.
What that commit failed to account for, however, is that there are
other circumstances where we end up with a subtitle is exactly the
same of the title. For example, when turning off Wi-Fi or mobile
broadband connections.
The behaviour of commit 9d75d777c7 is safe enough to be applied
on other device-backed connections, so do it.

When a window is in the background and should not have the cursor on top
of it, its _cursor will be null. By getting the texture through it, we
add this extra check, which was missing before, leading to a cursor
drawn at 0, 0 on windows where it should not have been drawn.
