Additional data points: The same issue arises with Isabelle2019 when I launch the interface using

	/Applications/Isabelle2019.app/Isabelle/bin/isabelle jedit

On the other hand, this invocation works fine:

	open /Applications/Isabelle2019.app/

I've tried rebooting, closing other applications (to free up resources), etc., but always seem to get this behavior.
