> Control question: did you click the icon on the left or on the right?

This is the first time I've ever been stumped by a simple read-only field. I think my confusion was due to the floating label animation on focus which I would expect only if the field was editable. You typically don't encounter read-only fields in mobile apps but they're common place in enterprise desktop apps.

Regardless, there is a bug since clicking the down arrow on the keyboard still allows me to select a state even though the field is read-only.
