### Expected Behavior

Actions Edit Window name should be descriptive so that Screen Reader users will be able to know that they are currently inside Actions Edit Window.
i.e. If user activate 'Edit' button of Copy Text actions, then Screen Reader should announce 'Copy Text 1 of 64 Ctrl + C Edit mode/Window'

### Actual Behavior

Actions Edit Window name is not descriptive as Screen Reader is announcing same info for 'Edit' Action view as for non-edit Actions view.

**Note Issue:** Same issue repro for 'Add New Action' pop-up window as Screen reader is only announcing 'Break into the debugger 1 of 67'

Start by reproducing the Actions > Edit and Add New Action flows with Narrator, following the steps in the issue, and inspect the settings UI entry points that provide each popup's accessible name. Done means the edit and add windows announce descriptive names that distinguish their purpose and associated action, rather than the same announcement as the non-edit view.
