Running tests locally on ChromeHeadless/Mac only runs half of them

When I’m running npm test locally on my Mac machine, it only runs half of the tests and acts as if that’s OK:

Chrome Headless 105.0.5195.125 (Mac OS 10.15.7): Executed 527 of 1059 (skipped 8) SUCCESS (3.908 secs / 2.019 secs)
TOTAL: 527 SUCCESS

What’s going on? There are no errors, no excessive skips, it just doesn’t execute half the tests for some reason. When I run other browsers like npm test -- --browsers Safari it runs all of them, so it must be specific to ChromeHeadless. I’m not sure how long it’s been this way but it’s super confusing.

@Falke-Design @jonkoops any idea what’s going on? Does it act like this for you too?

@Falke-Design looks like it’s triggered by the LineUtilSpec tests, they’re unstable — probably due to some race condition between before/afterEach and the custom remove/map init? There’s also a lot of repetition. This needs to be refactored…

OK found a quick solution for now, committing…
