Bug: Undoing Displacements Deselects them

[sheepy676]

Describe the bug

When Painting displacements with either alpha or geometry if you undo the edit you just made it will deselect every Displacement you undid but will still show them selected. You are also unable to select the Displacements again if you still have the paint window open. This makes using Displacements Really annoying.
