8.x: ComboBox items removed when typing filter quickly (possible bug?)

Hi, has anyone experienced the following behaviour?

  1. ComboBox populated with items.
  2. Text typed into the filter field very quickly (i.e.: “kkk” in a few tenths of second).
  3. No more items in the ComboBox (even after clearing the filter).

Verified with Firefox and Chrome on 8.1.2 and 8.1.3 (I don’t know about previous versions).

Also, it may happen locally, but it happens more frequently when connecting to a remote application.
(So it probably deals with timing and event processing? Just a guess…)

I think it’s a bug, because users cannot be forced to type “slowly” to prevent items the ComboBox to be emptied.
But I’d like to hear from other users, before opening a new GitHub ticket.

Thanks,

For an example, see https://demo.vaadin.com/sampler/#ui/data-input/multiple-value/combo-box: just type “kkk” quickly and all of the items will be deleted, even after clearing the filter.
