Windows Terminal version

main 5608cf1

Steps to reproduce

• open SUI and select Startup
• uncheck Use system default and try to change Launch position using up/down arrows

Expected Behavior

• set terminal launch position using up/down arrows

Actual Behavior

• controls not active unless a X/Y coordinate value is entered first:

Upon unchecking Use system default launch coordinates should be set to '0' and up/down controls activate.

ALTERNATIVELY:

As the title describes, when the Launch Position is first shown, give the current position greyed out as the x and y position.
When the Let Windows Decide is unchecked, un-grey out the x and y position and with each change of the x and y position, move the current window to match the new position. If I move the window on the screen manually, automatically update the x and y positions.
