[combobox][multiple-choice] Selection and removal behaviour

[erikkroes]

Expected behavior

When I select an option, I would expect a chip to be added to the textbox. I would expect "enter" to either pick something from the dropdown, or submit the entire combobox.

Actual Behavior

When I type "A" in the multiple-choice combobox, I can press "enter" to select "Apple". This fills the textbox with a "chip" -and- the text "apple". Pressing "enter" again removes both.
When a second chip gets added like (Pineapple), the textbox shows both chips and the text Apple,Pineapple.

I would like to repeat my advice to remove the multiple choice version as interactions have not been specified.

Yeah, this implementation is a demo of what would be possible (it states that if I'm right).

Can we maybe move this point to this discussion: #954 ?

Closing in favor of #954
