VWR-20696 ADDITIONAL FIX Fixed broken buttons in detached sidebar panels.

Buttons belonging items of some FlatListView instances didn't work (i.e. click on them didn't invoke the callback)
if the list was inside a detached sidebar tab.
I'm working around that by a simple XML fix (disabled focusing the broken buttons), but the issue needs further investigation.
Affected panels: avatar list, group list, teleport history.
