Color issues with zsh in wsl

So, I'm trying to setup oh-my-zsh inside a wsl terminal (using powershell as the console here, but I get the same issue in cmd). I think I setup all my colors correctly:

And when I run this:

print -P '%B%F{red}co%F{green}lo%F{blue}rs%f%b'

I get the expected:

But, my prompt is still wrong, as you can tell. I'm using the agnoster theme and the grey background on the pwd there should be blue.

Is there any way to see the escape sequences so I can determine if the problem is with the escape sequence vs the rendering thereof?
