marceltaeumel created an issue (squeak-smalltalk/squeak-object-memory#155)

Figure out a way to make strongly referenced objects in instances of `TextAction` weak as soon as they are pushed in to the text-edit (undo/redo) history.

We want to support long-living Workspaces where it becomes invisible that the undo history hogs on to probably expensive objects.
