Undo history seems to be unlimited, but redo history is not

Does this issue occur when all extensions are disabled?: Yes

- VS Code Version: Version: 1.128.0 (Universal)
- OS Version: Tahoe 26.5.2 (25F84)

Steps to Reproduce:

1. Hold down cmd+z for a long time (let it make like 100 undos)
2. Now hold cmd+shift+z for a long time (to redo all the changes back)

Expected behaviour: all the changes will be back, restoring the original state of the file
Actual behaviour: at some point "redoing" stops, eventually leading to a corrupted file state with only some of the changes successfully re-applied.
