SpaceAnalyzer: Fix the crash caused by using arrow keys

Browse source 
Previously, SpaceAnalyzer set focus on the selected BreadcrumbButton.
Using arrow keys triggered the keydown_event of the AbstractButton,
which later on caused a Function object to be deleted while it is still
being used.

This change sets the focus on TreeMapWidget and adds an event handler
to TreeMapWidget for keydown events.

Fixes #13254.
