Extra paddings when running in Docker

What happened?

I'm creating a devcontainer at work and I wanted to include my oh-my-posh theme in there too, but it seems that running oh-my-posh in Docker renders something different than expected.

Expectation	Reality

Note:

1. how on the left prompt there's an extra space between the prompt and the cursor
2. how on the right prompt there's an extra space between the prompt and the terminal window

Here's a repository to reproduce the problem https://github.com/TommasoAmici/oh-my-posh-docker-bug-report

Theme

I made a minimal theme to reproduce the problem:

@TommasoAmici pretty sure this isn't an issue with oh-my-posh but something else. Why? rprompt in zsh is native, so we only provide the string (no extra padding logic in there). Same for the regular prompt. Something is influencing the windows size inside the terminal and confuses zsh.

[JanDeDobbeleer]

@TommasoAmici for reference, this is your config running inside a devcontainer in vscode:

[TommasoAmici]

thanks for the extremely quick reply. Interesting. I guess there's not much I can do then.

Yeah that's how it looks like for me in vscode
