Steps to reproduce
- Go to https://www.mediawiki.org/wiki/Developer_Advocacy
- Click "Edit Source"
- Switch to "Visual Editing" and make a minor edit
- Do not try to save your changes just to reproduce this bug ;-)
- Instead, click "Review your changes"
You will notice in the "Review your changes" dialog, changes to be published showing content (wrapped in translate tags) that hasn't been touched and will be removed.
It is not the first time that I've experienced this issue. I'm wondering if the editing of translatable pages in VE is not supported, then why we allow switching to the VE mode on these pages?
