oh-my-posh: `parentBackground` breaks last symbol in `powerline` and `diamond`

Code of Conduct

What happened?

1. Let’s take the default Aliens theme.
2. Change a background field to parentBackground like in my images below.
3. We’ve got a glitch.

I’ve been using Oh My Posh from the very beginning, just upgraded from an old version. While it doesn’t give me the same depth of control as the PowerShell version did, to be honest, it still makes me very happy. Thank you for creating a great tool.
