### Expected Behavior

User should be able to Select commands using 'Shift+ right/Left arrow keys' inside Command Prompt, which is happening in 'Windows Power shell' tab.

### Actual Behavior

User is not able to Select commands using 'Shift+ right/Left arrow keys' inside Command Prompt.

Start by reproducing the issue in a Windows Terminal Preview Command Prompt tab using the listed Windows build and the Shift+Right/Left Arrow steps. Compare selection behavior with a Windows PowerShell tab, then trace the Command Prompt keyboard and text-selection handling. Done means both Shift+Right and Shift+Left select command text as expected, including for keyboard users.
