Hello,
we are encountering the following issue with the "image upload/edit" function of the TinyMCE extension.
Everytime someone wants to add/edit an image to a page with the TinyMCE function it clears all properties of the image except for the title. This is especially annoying when it comes to width and heigth of the image, because it defaults to the uploaded size.
We are running Mediawiki on version 1.40 and the TinyMCE Extension is on version 1.1.2 (9e1176b).
