Wrong / double escaping of podcast titles

[poschi3]

Expected behavior

If I add a podcast and set a big title with a & I get it double escaped in some places (e.g. podcast title, player, feed):

Actual behavior

Right escaping on every location

More information

I also have strange behavior I'm not able to explain. If I change a title after initial set it gets sometimes copied to other locations or on rendering is taken from different? I made a short video to show what the strange behavior is:

System information (see Podlove > Support menu)

I tested it local in docker and on my production instnace

1 FEHLER: 
- Du verwendest die Standard-Permalink-Struktur von WordPress. Das könnte einigen Podcast-Clients Schwierigkeiten bereiten. Gehe zu http://localhost/wp-admin/options-permalink.php und setze die Einstellung auf etwas anderes als die Standardeinstellung (z.B. auf "Beitragsname")

Nice, Everything looks fine!

It's the Gutenberg editor. I have the beginnings of a fix in the linked PR but it needs more work. Until then, if you use the editor in "code" mode, that seems to help. Maybe that's a temporary workaround for you.

I'm confident now that it's a bug in WordPress (see WordPress/gutenberg#20490) and I'm not sure I can or should fix it on the Publisher side. Because it may break again if WordPress fixes the bug eventually. However the timeline is unclear because the bug exists since early 2020 🤷‍♂️
