dragging icon to dock won't open file if the app is already open
2020 M1 MBA running 11.3.1
when I drop a document on an app icon in the dock, the file doesn't open if the app is running.
Instead I get the below image - which seems to be a list of past documents the app has opened. If the app is closed the document opens normally. I tried disabling "Force Click" on the trackpad, following another thread on the help board, but that didn't work.
If an app is **not** running dragging a document onto the dock icon works normally.
