I have recently encountered a problem when using the Google Docs Add-on:
When I insert a citation (either with the keyboard shortcut or paperpile menu), the focus in the dialog is lost after ~1 second, but only if there was a text selection. If no text was selected, the add-on works fine. With text selected, the focus is there for ~1 second, and I can type text into it, but then focus is lost right away. I don’t recall this happening before.
