Issue: when using Visual editor in RTL wikis (observed in hewiki and arwiki), The editor pane is displayed as LTR.

peeking in the html source, i see this, which is clearly not right:

<div class="ve-ce-branchNode ve-ce-documentNode mw-content-ltr mw-parser-output" contenteditable="true" spellcheck="true" data-gramm="false" lang="en" dir="ltr">

peace
