Steps to reproduce:
Go to enwiki, and using the Android application, add the string "https://example.xyz" to any page
Expected result: The message at MediaWiki:Spamprotectiontext is displayed as parsed HTML
Actual result: The message at MediaWiki:Spamprotectiontext is displayed as a wall of unparsed wikitext
Tested with: Android 9 with app version 27.50341-r2021-02-02
@Dbrant The message looks good on 2.7.50358-r-2021-05-11, but there is still a publish button on it. I'm not sure if that should be there. Pressing seems to have no effect.
Yep, that's expected: certain types of errors are warnings, and should allow the edit to be resubmitted. If it's more severe than a warning, then tapping Publish will just show the same error again.
