Limit dash docs to 50

Browse Source 
We has poor performance if we try to allocate hundreds of actors;
a bit more ideally, we'd keep pulling as much as we can, but really
no one should have more than 50 in the list as is now except on
unreasonably large screen sizes.

In the future we should change this to be pull-on-demand thing
in a chunked fashion.
