Insert appears not to work with CKEditor 5 #22
Description
When trying to insert a link to a document attached to a node (a pdf for example) into the Body field (CKEditor 5), it doesn't work.
Instead this message is displayed in the developer console of Google Chrome:
insert.js?sggjji:198
Uncaught TypeError: $pane.size is not a function
at Object.activateTabPane (insert.js?sggjji:198:15)
at Object.insertIntoActiveEditor (insert.js?sggjji:177:23)
at HTMLInputElement.insert (insert.js?sggjji:106:21)
at HTMLInputElement.dispatch (jquery.js?v=3.7.1:2:40035)
at v.handle (jquery.js?v=3.7.1:2:38006)
I tested this with a fresh build in tugboat, but had experienced it on several recently-updated sites (to Backdrop 1.28.2).
