Markdown formatting gets lost when editing a message

### Steps to reproduce

1. Activate Markdown Formatting under "Options" (it is deactivated by default)
2. Write a message with fornmatting like **bold text** or so, and send it.
3. Edit this message. The editor window shows the formatted text. Whatever I change now, the result will be 100% unformatted, all formatting is unrecoverably lost.

### Outcome

#### What did you expect?
I expect that the editor window in "edit message" mode shows the formatting characters explicitly (like in original editing field), not the formatted text without formatting symbols. Like it is now, I cannot edit the formatting in the first place.

#### What happened instead?
Although editor window when editing message shows formatted text (without formatting characters, which is a bad idea as said above), after editing all formating is lost.
