CKEditor: Checklist for manual tests

Work in progress - list of things to manually test with new versions of CKEditor 5. If something's missing, please complement, or report in our chat.

Core functionality

Link dialog and balloon toolbar
Image dialog (open it, upload or select image and insert, replace image)
Image caption toggle
Image alignment
Image drag-and-drop upload
Styles configuration and usage in content
Try different editor toolbar setups (less toolbar buttons, more toolbar buttons, different button combinations)

Code block indent lost

Add a code block (pre) to content, which contains indentation. Save the node, open the node form again.

Correct behavior: Code block indent is the same.

Lists trigger reformat warning

Add a list (ol or ul) to content, save the node, open the node form again.

Correct behavior: Editor initializes without warnings, the list is unchanged.
