Fixes #7828
Description
Per the documentation, "Items added to the ComboBox are wrapped in ComboBoxItem containers.".
Since we were already wrapping the provided TextBlocks in ComboBoxItems before adding them to the ComboBox control, the items were wrapped twice, and Narrator did not handle this behavior correctly.
Adding TextBlocks to the ComboBox directly fixes this issue, and Narrator will announce "Snooze for 5 minutes ComboBox collapsed" as expected.
