I am trying to use WebItems in page editor, looks like system.editor.precursor.buttons is the only option available.
Unfortunately, this completely breaks the Confluence UI. When an app is installed, the default icons alignments are messed up and Unrestricted text appears (see screenshot).
I totally understand your point. I don’t think that changing the priority will lead to a faster resolution on this one.
After commenting here, I’ve sent a message to the team responsible for this fix asking for an update. If there is any news, they will update the ticket directly.
