Combo showing single-option popup while readonly in OS X

http://webix.com/snippet/2916f4f0

If I focus the view and press the Cmd key in OS X, an options popup will show containing only the selected option.

Is this intended behaviour or some OS X weirdness?

I can confirm the issue, we’ll fix it.
As a workaround, you can prevent this behavior using onBeforeShow event for the popup and onBeforeSelect for the inner list:
