Environment

Windows build number: 10.0.19041.388
Windows Terminal version: 1.2.2022.0

Any other software?
wsl 2
zsh 5.4.2
tmux 3.2

Steps to reproduce

Open tmux with custom colors theme in Windows Terminal official and preview version

Expected behavior

Expect the colors to be the same in official and preview version

Actual behavior

The colors are correct when using just zsh, but wrong in the preview version when using tmux.
It looks like the zsh prompt colors are still correct, but anything set in .tmux.conf is wrong.

Official windows terminal:
wt_official

Preview windows terminal:
wt_preview

I had this in my tmux config to enable truecolor:
set-option -ga terminal-overrides ",rxvt-256color:Tc"

After removing that it looks good in both official and preview version.
