Comment 7 for bug 2000270

Mike and I ran into similar issues with the keyboard interactions while working on the upcoming combobox-based MARC editor, and we have some changes in that branch that might make it easier to add some logic around disabled entries. That will be forthcoming early next year.

I have been sorely tempted to rewrite combobox entirely using the demo at the end of this article: https://adamsilver.io/blog/building-an-accessible-autocomplete-control/

... but we use it for an awful lot of things, some of which I'm not totally familiar with yet.

The org selector's labeling logic has changed quite a bit in the last few weeks, but I don't plan on making further changes to it unless something else comes up.
