Insert and undo a note leads to "corrupt" measure

In an empty measure (I used both 2/2 and 4/4) insert a rest,
then enter a note
press escape (to exit note entry mode)
add press ctrl+shift+letter to insert another note
undo (probably because you really wanted to make a chord rather than insert a note😉)

Result: the last note added is deleted and the rest at the beginning of the measure is gone.
Expected: Only the last note entered should be gone.

The good news is that selecting the measure and pressing delete will restore the measure to its normal state.

If you look at measure properties while it still looks wrong, it will report an unchanged measure duration.

Closing and opening the score while it looks corrupt will fix the issue. I made it Major rather than critical for this reason.
