It seems like DA1 is broken in this release. When I query Sixel support by sending \x1b[c, the response doesn't include a valid CSI (\x1b) in the beginning:

[?61;4;6;7;14;21;22;23;24;28;32;42c

and it should be:

\x1b[?61;4;6;7;14;21;22;23;24;28;32;42c

I'm using Microsoft.WindowsTerminalPreview_1.22.2362.0_arm64.zip

This is probably “the documentation said I can read VT replies without enabling VT INPUT mode, but the new ConPTY breaks that” as reported by @alabuzhev

We drop the ESC during processed input handling. See discussion in #17729.

Avoid dropping Esc characters from VT responses (#17833)
be99f93 
`GetChar` checks if the vkey is VK_ESCAPE. `CharToKeyEvents` however
tries really hard to figure out the vkeys of all characters.
To avoid these issues all we need to do is to simply use the existing
`WriteString` function we already use for all other VT responses.
If it's good for conhost responses, it's good for ConPTY responses.

Additionally, this removes another `IsVtInputEnabled` which was
redundant with `WriteString` which worked exactly the same internally.

Closes #17813
Closes #17851
Probably also related to #17823

* Wrote a small app to send and receive a DA1 request. It works ✅
* WSL already worked to begin with (and still works now) ✅
* No double-encoding of mouse input events ✅
