The "Insert Markup" feature is broken. This occurred fairly recently.
I'm using the Legacy Editor. When I choose "Insert Markup" and enter any text and then click "Insert", the form goes blank (no text in it) and nothing is inserted. The dialog stays open. Only way to close the dialog is to press cancel. Closing the dialog does not result in text being inserted.
This must have happened in last few weeks. last time I used it was a couple weeks ago I think. This is a very important feature for us.
Any ideas how to work around this?
