### Expected Behavior

Name of 'Tab Title' edit field should be defined.
i.e. For 'Windows Terminal' tab title, Screen Reader should announce 'Rename Tab Title edit '

### Actual Behavior

Name of 'Tab Title' edit field is not defined.
i.e. For 'Windows Terminal' tab title, Screen Reader is only announcing 'edit '.

**Note Issue:** _Screen Reader is only announcing 'Edit placeholder' for 'Window 1 Enter a new name' edit field inside 'Windows 1' pop-up._

Reproduce the issue in Windows Terminal Preview with Narrator using the listed rename-tab shortcut, then inspect the Rename Tab/Window edit-field UI. Done means the tab-title field and the Window 1 dialog field expose descriptive names, such as “Rename Tab Title,” when announced by the screen reader.
