[Editor] Assets path does not get Updated in the breadcrumb bar on deleting an asset from the project window.

Assets path does not get Updated in the breadcrumb bar on deleting an asset from the project window. The deleted assets path appears in the breadcrumb bar for both One Column mode and two-column mode.

2. Project > Create > any asset > Observe created assets name in breadcrumb bar
3. Delete asset created in step 2
4. Observe the name of that asset still appears in the breadcrumb bar.
