Current Behavior

Narrator sometimes reads out the combobox selection twice.

Observe:

• Narrator reads out the selection twice

See recording. The first time I try everything is A-OK. The second time the issue repros.

It reads: "Fruits Group Apple 1 of 7 Selected Apple 1 of 7 Selected" Notice: "Apple 1 of 7 Selected" is read out twice.

We have had bug filed on us on both on windows narrator and safari voice over.
