Bug: Editing a post corrupts HTML escaped characters

[Krinkle]

Environment:

• OS: 17.3
• IceCubesApp version: 1.10.31

Description

• Publish a post in which a non-breaking space is used (for example). In my case I drafted it elsewhere and then copy-pasted to the app for posting.
• Some weeks later (ie move to other feed, quit app, reopen app, find post).
• Edit the post to make a trivial change.
• Notice the space has turned into a doubly escaped character, thus showing raw HTML to end users.
