I could not find any solution for this bug. And I also did not find any MultiSelect widget that consists of a combobox and a listbox (like ours) that works well with VoiceOver and Safari. Even the W3 example is not working properly.

There are several Webkit bug reports that seem to be related to this issue, e.g.

• https://bugs.webkit.org/show_bug.cgi?id=231724
• https://bugs.webkit.org/show_bug.cgi?id=167671

And there are bug reports for other libraries like e.g. Angular Components: angular/components#24390

I'll keep an eye on the linked issues and update this bug if there's a solution.
