Exiting Select and Mask resets toolbar groups to the last tool in each group

Photoshop version: 28.0.1 20261014.m.3714 ae936ff, x64 (beta, PublicBeta)
Operating system: macOS 15.7.7
Hardware: Intel Mac, 16 GB RAM, Intel Iris Plus Graphics 655

Steps to reproduce:

1. In the main Photoshop toolbar, select tools within tool groups, such as the Brush Tool in the Brush/Pencil tool group.

2. Open Select and Mask.

3. Exit Select and Mask and return to the main Photoshop workspace.

4. Check the tools displayed in the main toolbar.

Expected result:
Each toolbar group should retain the tool selected before entering Select and Mask.

Actual result:
The tool selections are reset across the toolbar. Each group displays the last tool in its flyout list instead of the previously selected tool.

Frequency: Every time I use Select and Mask.

The change is visible after returning to the main workspace. I cannot determine exactly when it occurs because Select and Mask has its own toolbar.
