This PR is not needed because it is not a bug:
#2644
#2717
Close it.

After testing this bug does affect windows powershell, see #2862.

I believe that this change will fix powershell and not adversely affect any other platform. If someone has the chance to test with a mac I would appreciate it.

[MadVikingGod]

I would also like to point out that the reason this PR should be considered while the first two PRs weren't is this description has enough information to reproduce.

We welcome both bug reports and PRs, but we need to know why a change should be made. If you start with a bug report before or at the same time as a PR then we can get the reasoning behind the change.

@MadVikingGod are you able to verify this PR resolves #2862? I have verified this does not change the working behavior on a Linux system.

[MadVikingGod]

Yes, this does fix the powershell, and it doesn't affect mac or windows linuxs
