Undoing doesn't work when inside a number field

When the user is editing a number field and Without exiting (see recording ARC number field undo) decides to undo their edit, it will undo previous edits and not the number field. This is different from other places in the editor, such as when editing Transform values (see recording Transform number field undo)

Repro

1. Create and open an ARC
2. Change any value
3. Click on a number field for any different value to start editing
4. Change the value to any new number
5. Undo without exiting (see recording)

Expected: The value the user is editing is changed back to the previous value and is exited from editing the field

Actual: The undo is done for values previous to the one the user is currently editing
