SpaceAnalyzer: Fix the crash caused by double click

Browse source 
With #12480, Breadcrumbbar's on_focus_change() uses
on_click(). In SpaceAnalyzer, double clicking triggers the
TreeWidgetMap's on_path_change(), which triggers Breadcrumbbar's
on_focus_change(), which also triggers the TreeWidgetMap's
on_path_change() again. This resulted in use-after-free of
Breadcrumbbar, thus resulted in the crash. Not updating the
TreeWidgetMap's viewpoint recursively solves the issue.
