clear screen when launching escape-artist on Windows

Related to #8 (comment), I'm seeing something similar but I'm not catching the escapes that are doing the clear screan. This is what I see.

The difference may be that I have a print 'Hello, from blah' in each of my files when launching nushell but you'd think that the clear screen would come before those and escape-artist would capture it. 🤔

Isn’t that eraser icon in the first line clearing the screen?

[fdncred]

Yes, of course you're right. It is the 2J.

Here's pwsh, just for fun. It does the same thing in WT 1.19.10821.0 and 1.20.10822.0.

Update: It does the same thing with pwsh in wezterm and alacritty too.

Interesting. If this is happening in multiple shells, I wonder if it’s a portable_pty thing…

[fdncred]

Multiple shells and multiple terminal emulators. You may have a correct guess.

I skimmed the portable_pty code and didn’t find anything obvious. Possible this is happening in the Windows ConPTY library itself…

I'm guessing it could also be a response to the 3 CSI calls before it?
