Using WP 3.3.1, if I add a custom style float: left; to the image editor in the Styles field it does keep it on the initial update. However, if I go back to edit the image, it removes that style that I added. I tried with both the TinyMCE Advanced plug-in activated and de-activated so it's not that plug-in causing it.
I want to use the style so that the image will float left no matter where the post content is seen.
I am using a Twenty Eleven child theme with nothing modified within the Admin parts and my role is that of Administrator.
I'm just wondering what I would need to do to keep it from removing the style if I click on Edit Image in the Visual Editor. It's just annoying especially if I forget to re-add it.
