[Win32] [Accessibility] [11yMAS] [MAS2.4.5] [Alternative way is not provided for the user to close the pop up.]

[DasaradhaKamjula]

User Experience: User who rely on keyboard will not be able to close the dialog box without navigating inside the pop up.

Test Environment: OS Build: 16299.19 Excel version:1712(8808.1000) Prerequisites: Add script lab “Add ON” In Excel

Attachments: MAS2.4.5_Alternative way.zip

Repro Steps:

1. Open Script Lab in Excel
2. Navigate to Code button and activate it.
3. Navigate to Code pane Using F6 key
4. Navigate to “Delete” control and activate it.
5. Verify user is able to close the "Delete pop up" using Esc key or not .

Current Behavior: Delete pop up is not getting closed with Esc key. User should navigate inside the pop up and has to press enter on cancel to close the pop up.

Expected Behavior: Pop up should get closed using ESC key which is consistent behavior. More than one way should be provided for the user which will reduce the Burden on the user.

Note: 1.Same issue repro throughout the application, User is not able to close the popup using ESC key. 2.All the above issues are repro for the Word and PowerPoint also.
