The old image dialog allows to select non-image attachments

STEPS TO REPRODUCE

STEPS TO REPRODUCE

1. Upload some image and non image attachments to a page (e.g. some .txt files)
2. Edit a page (or same page) with CKEditor
3. From toolbar, click Image > type txt in the search, or open the document tree and expand the tree to the previous page containing the attachments

EXPECTED RESULTS

1. The search does not propose a non-image result
2. The Document tree shows only image type attachments and/or the "Select" button is enabled only for images.

ACTUAL RESULTS

1. The search results propose non-image results
2. The tree displays also non image files and the "Select" button is enabled as well for them.

They can be selected, but they end up in "Edit Image" dialog, for which settings do not apply. If inserted anyway, a blank canvas is displayed on which the name of the file appears after page save.
