We can use that newer method where we don't care about the actual position
of an element inside the array.
(Array.includes() and Array.indexOf() do behave differently in edge cases,
for example in the handling of NaN, but those don't matter to us)

Users already have to trust their OS, so asking whether an OS component
should be allowed to perform an OS operation is odd at best, if not
confusing. Account for this by allowing system components that require a
keyboard grab to work - namely Setting's keyboard shortcuts panel - to
do so without triggering the permissions dialog.
