When editing a comment and submitting, the text turns into a string of garbage text like so:
%3Cblockquote%3EI%20think%20those%20creatures%20represented%20Job%E2%80%99s%20trials%20and%20and%20everything%20in%20it2C%20I%20make%20the%20rules%2C%20and%20you%20are%20just%20as%20much%20my%20crddddddeature%20as%20these%20are%2C%20at%20which%20point%20Job%20stops%20questioning%20His
Refreshing the page clears the garbage text. This doesn't occur in my case when I'm editing comments as an admin, only in user cases. This occurs across different browsers too.
