I have some custom BB codes that used to stay in background while directly applying formatting to the text in messages. Say, an [H1][/H2] pair of tags would format text as a heading while hiding the tags themselves. This would work both when creating a message and when editing it. After updating from version 1.5.7 to 1.5.8 I noticed that the formatting is no longer applied to the text in the edit mode, instead one sees plain text with BB code tags in it. The direct formatting in the edit mode still works though when creating messages. What's the possible cause of this change of behavior? Does the problem lie in XF, or should I fix things on my side?
