[Windows] OSC sequences don't give any response

[TheLeoP]

What Operating System(s) are you seeing this problem on?

Windows

Which Wayland compositor or X11 Window manager(s) are you using?

No response

WezTerm version

20240730-082727-56a27e93

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

OSC escape codes that should output a value, don't output anything

To Reproduce

1. wezterm
2. powershell (other shells like git's bash or wsl ubuntu's bash behave in the same way)
3. "$([char]0x1b)]11;?$([char]0x07)"

Nothing is printed

The equivalent steps on wls ubutu's bash would be

1. wsl
2. printf '\x1b]11;?\x07'

Nothing is printed

Configuration

no config

Expected Behavior

The corresponding value should be printed by the terminal (in this case, the response containing the color of the terminal's background)

Logs

No response

Anything else?

OSC that do not return a value work as expected. For example, "$([char]0x1b)]11;#00ff00$([char]0x07)" does change the terminal background color to green

This seems to be a current limitation of ConPTY (upstream issue) as per:

microsoft/terminal#3718
and
microsoft/terminal#16990 (comment)
