Extra whitespace when running jest tests in a PowerShell window.

[Butters646]

I don't know if this is specific to jest, that is just how I observed this behavior. I get large "chunks" of whitespace in my terminal session when I run my tests. This doesn't happen when I use PowerShell directly or when I use the command prompt in Windows Terminal, so it looks like it is an issue with the PowerShell window in Window Terminal.

I have attached screenshots of the issue. This is just one example of the extra space. Huge chunks of blank lines appear throughout the run in the PowerShell window.

This is very unexpected. When you run it in a normal powershell window, does the size of the window change?

[Butters646]

@DHowett It doesn't appear to. I see no observable window size changes.

@Butters646 could you share your powershell profile? I've got a theory that some customization in there is what's tripping the Terminal up

Sure. Attached.

that'll do it!

alternatively, don't force the screen or buffer size in the file that powershell runs for every new session (including when it's spawned by other poorly-behaved tools sometimes!)
