LrC 15.4.1 UI Issue: Closing Remove Tool leaves gray panel area; fails to redraw Edit/Basic panels.

·  Title: LrC 15.4.1 UI Issue:  Closing Remove Tool leaves gray panel area; fails to redraw Edit/Basic panels.

·  Product: Adobe Lightroom Classic v15.4.1 Release (Camera Raw 18.4)

·  OS: macOS 25.6.2

·  Description: In the Develop module, using Solo Mode with the right panel visible, activating and then closing the Remove (spot removal) tool completely breaks the right panel interface. The panels vanish into a blank, dark empty column. Global panel keys (F8, Shift+Tab) and top menu toggles fail to restore it. 

Workaround: Clicking the Edit icon (sliders) manually, or toggling Crop (R) or Masking (M) or Red Eye Removal icons on and off forces Lightroom to redraw the UI, successfully bringing the Basic and edit panels back.   Exiting the develop module to the Library module, (G or E) and then re-entering the Develop module (D) will also bring back the Basic and edit panels.

·  Camera model:  N/A

·  Steps to Reproduce:

1. Open Lightroom Classic 15.4.1 in Develop module with Solo Mode active.
2. Click the Remove tool icon (note that all but the Histogram and the local edits options disappear at this point. 
3. Click "Close" on the floating tool panel does not result in reappearance of the missing Basic/Edit panels.

·  Expected Result: The right-hand panel column returns to showing the Basic/Edit panel headers.

·  Actual Result: The entire right column turns into a dead, blank black space.  If the panel toggles (via menu or shortcut keys) are used thee remove panel and histogram closes and reappears.  When closed, the right panel location is grey.
