Current behaviour

Steps:

1. Write the numbers (could be any text)
2. Press cmd + delete repeatedly to delete the text
3. Press cmd + Z to restore -> but it only restores a part of it (all excpet the last line)
4. Now the second try
5. Do everything again with the only difference being, that after the last number you press enter one more time, so you have one more new line
6. Result: Now it works as expected

What is even weirder now:
After I've done that I test the behavior with words in one line (see second video).

1. Type words
2. press cmd + delete
3. Press cmd + Z -> instead of restoring the last words it restores the numbers from a few minutes ago... really annoying if you lose your text irrecoverably with one accidental cmd + delete

Expected behaviour

Cmd + Z should always restore the full deleted text
and if you press cmd + Z once too often cmd + Shift + Z should work reliably (which it doesn't either)
