@Sukhendu2002 Thanks for the PR. Shouldn't we update this file as well /editor-style-rtl.css?

[Sukhendu2002]

It looks like other themes only use body: would that work here?

@carolinan Thanks for the suggestion! The body selector is working fine in this case, so I have updated the PR accordingly.
