Windows Terminal version

1.14.1962.0

Windows build number

10.0.19044.1826

Other Software

Screen version 4.08.00 (GNU) 05-Feb-20

Steps to reproduce

Start a new Ubuntu bash shell in Windows Terminal.

run "ls -la" several times until the content scrolls off the screen. Note the presence of the scrollbar on the right, and the ability to use the mouse wheel or the scrollbar to scroll back through the content.

Start "screen" via "screen -D -RR".

In the screen session, perform the same "ls -la" steps above. Note the absence of the scrollbar on the right, and the inability to use the mouse wheel or the scrollbar to scroll back through the content.

Expected Behavior

One should be able to scroll back through content independent of the program being run or the TERM environment variable setting (normal bash: xterm-256color; screen: screen.xterm-256color).

Actual Behavior

One loses the ability to scroll back through content once inside "screen".
