I don't understand

That is the patch that generated the exception I posted.

I look forward to contributions to improving the dialog.  Redoing the font tab is #24776.  The highlight tab is #24781.  The latest mockups look like improvements to me, but we can discuss further.  (#24781 also has Mark's proposed refactoring of the dialog code, but I have not reviewed in detail.)  There are numerous issues connected with key definitions.
