Inability to delete latest auto-save revision

Hi, I am occasionally facing a strange problem where latest auto-save simply cannot be deleted no matter what. And the annoying notification message appears on top, tempting me to switch to (discarded, changed my mind, no longer proper) version of my post, which I no longer desire.

Then, trying to delete that auto-save is not apparently possible. Please, check screenshots.

How To Reproduce:

Essentially, you can try switching between classic and new gutenberg editor, poke around just enough for auto-save to kick in, then leave editing (confirm js alert), and later when you back to editing, you will see that ‘newer auto-save’ version is available, which you discarded minutes before. Try to delete it and it will fail.

Any chance to fix this?
