Something must have changed in webpack because that's the only thing that's been changed since the tests succeeded.

It could also be a different Windows or Chrome version 🙄

[rouke-broersma]

The issue indeed appears to be chrome versions..

Windows agents: 113.0.5672.64
Linux agents: Chrome Headless 112.0.5615.165
My local wsl: Chrome 113.0.0.0 (Linux x86_64)

Seems that the results are different from chrome 113, but the linux agents have not yet been updated.

@hugo-vrijswijk @nicojs how do we want to deal with this? Create OS specific tests until the linux agents have been updated? Ignore the tests until the linux agents have been updated?

sut.element.themeBackgroundColor.trim()?

I've applied the trim for now, let me know if this is not how we want to fix this.
