Comment (by peterwilsoncc):

 Thanks @flixos90, I'll review the PR with a view to committing this over
 the next few hours.

 > While I definitely think we need to fix the duplicate logic execution
 here that causes the bug, calling `wp_filter_content_tags()` twice is a
 different topic. This is not something that should be done, WP core
 doesn't do it, and we also expect other `the_content` filters for example
 to not be run twice.

 Agreed.
