Steps to reproduce:
Open a workspace.
Type: foo
Press: Home key
Press: <cmd>z
Expected behavior:
The text in the workspace will abandon, and the textmorph will not have unaccepted changes.
Actual behavior:
The text in the workspace remains, but the textmorph does not indicate unaccepted changes. You cannot press <cmd>z again to revert the empty state of the textmorph.
Not yet further investigated ...
