Short description of error
When sculpting, pressing undo will change the brush type and the brush settings to the previous selection.

The issue has existed for me for several years across multiple PCs, and countless versions of Blender. It has been reported here by many people but I've never seen anyone mention the following which I think could be helpful. I always work with a second window on another screen with just a UV Editor open which I think has something to do with the issue.

For example, in a new scene, start with the Draw brush active and change to the Grab brush then make three brushstrokes on the corner of the cube with it to pull it out. Pressing undo once will only remove the last Grab brushstroke as expected but also revert the active brush to the Draw brush which is not expected.

After loading factory settings, the problem doesn't exist. What causes it to happen is if you add an additional New Main Window and set it to the UV Editing workspace and combine the UV Editor area and the 3D Viewport area to make just one large UV Editor area. Repeating the previous steps mentioned in the Sculpting workspace then causes the issue to happen.

There is some inconsistency with what happens afterwards with regards to changing the windows, workspaces and areas around. It seems various combinations can cause this to happen but the following steps should consistently replicate the issue for anyone on factory settings.

Exact steps for others to reproduce the error

File > Defaults > Load Factory Settings
Window > New Main Window
On the New Main Window, select the UV Editing workspace
Combine the two main areas so only the UV Editor area remains, covering most of the workspace, and the 3D Viewport area is removed
On the original Main Window, select the Sculpting workspace
Select the Grab brush
Make three brushstrokes
Press undo once
Observe as one brushstroke is removed as expected but the brush type is also changed back to the default Draw brush

Additional observation:

Close the New Main Window that has the UV Editor open
On the original Main Window, select the Sculpting workspace
Select the Grab brush
Make three brushstrokes
Press undo once
Observe as one brushstroke is removed as expected and the brush type does not change

I can confirm the problem, and indeed the "New Main Window" is needed to replicate it.
