P: Healing brush does not work on SolidColor layer mask after Revert command

Healing brush does not work on SolidColor layer mask after Revert command.

How to reproduce.

Create a new document, create a SolidColor layer with a mask.

Switch to the layer mask (alt+click).

Draw something with a black pencil on the mask (like lines and dots).

Select the healing brush and check that it works for the mask (remove some dots).

Save the document.

Do any action to appear in history.

Execute the Revert command.

After this command, the healing brush on the mask of this layer will not work.

If the file is saved and opened in a new way, then it is on this layer, on its mask, that the healing brush will not work.

Tested on photoshop CS6 and CC2020 (Windows)
