 > there are five spaces in the broken code that are actually non-breaking
 spaces

 Yes, this is the same feature (bug) in the browsers trying to keep empty
 spaces typed by the user in contenteditable. In some cases and in some
 browsers these invisible non-breaking spaces are inserted at many
 different places. Unfortunately it is impossible to "guess" whether the
 user intended to insert a ` ` or the browser just added it, so fixing
 this is pretty hard/prone to edge cases.

 This works much better in the block editor now. Closing as worksforme as
 it is the expected browser behaviour in contenteditable. Feel free to
 reopen with ideas about how to make it better in the classic editor, if
 still needed.
