Steps to reproduce:
- Go to a wiki that is in RTL (or change your preferences to make an RTL language the default)
- Start to write a message using Convenient Discussions and use <syntaxhighlight> tag.
- Observe the message preview.
Actual outcome: The preview is shown code in <syntaxhighlight> with LTR direction, but RTL position
Expected outcome: The code should be in RTL position
When saved, the direction is fixed.
