New report of OSC 12 with symbolic name not working

[DHowett]

    @DHowett @mattwojo sorry to dig this old thread up, but if I do a `printf %b '\e]12;red\a'`, should I expect the cursor color to change to red?  Using terminal preview version 1.16.2641.0, doing the above in wsl, I don't see the cursor color changing.  It retains the original color specified via the color theme in the settings.

Interestingly enough, if I lock my screen (Windows-L) and unlock it the cursor has then changed its color.

after locking and unlocking:

I bet we don't do an invalidate of the screen.

Nah I dunno what this is. We should move this over to the Terminal repo cause I see this too. Even with the rgb: specs too.
