Scrollback buffer doesn't work with screen

[wmertens]

Environment

Windows build number: 10.0.19041.172
Windows Terminal version (if applicable): 0.10.781.0

Any other software? GNU screen in WSL2

Steps to reproduce

I have the following in my .screenrc:

  termcapinfo xterm*|xs ti=\E7\E[?47l

This makes it so screen doesn't internally scroll but instead just lets lines go out into the terminal, so that I can scroll the terminal buffer which is bigger and faster than screen's buffer.

Expected behavior

This setting works in all terminals I've used so far, including Hyper

Actual behavior

In Terminal, the setting has no effect, and the screen scrollback buffer doesn't flow into the terminal scrollback buffer.

This is the intersection of a couple different issues.

• We don't support alternate screen buffer through private mode 47 (we support 1049) -- tracked in DEC private 47/1047 not supported (alt buffer) #3082
• When there's a scrolling region, even if it touches the top of the screen, it doesn't push lines into the scrollback: Scrolling within regions that include the top of the screen doesn't push lines into scrollback #3673

/dup #3082 #3673

Thanks!
