In Plone 6.0.9, if the first element in the rich text field is a link/anchor tag, tinymce appears to give it the attribute data-mce-selected="inline-boundary". This means its selected as soon as you open the page, which in Barceloneta is a blue background. A client is requesting that it not do this because in their mind they haven't selected it yet.
This is a noob question, but can I assign a callback function after tinymce init somewhere, so I can change that attribute? I tried putting this in a plugin but it looks like these are loaded before the tinymce dom is built.
