Caolán McNamara dd46727b99 Resolves; tdf#87120 no keyboard navigation inside floating windows 
lets try and treat these the same as we do normal toplevels
like dialogs if they popup with GrabFocus.

This way focus can be set on widgets inside the floating windows, and
so keyboard traversal of widgets etc all works.
