In Safari, open the details of an event and click on one of the multi-select fields (e.g. presenters, contributors). This will open up a dropdown which hides already selected values. This is not desirable. Like in other browsers, the dropdown should only open after clicking the field an additional time.
[...] Arguably a better solution would be to get rid of entirely, as it is not well supported.
