I think the fullname filter was meant to be an array of fullnames to the test, with possible wildcards. That is @("describe1.describe2.test1", "describe45.context1.test20") so you can copy paste it from the normal output and use it without providing arrays in arrays. This was meant for interactive use and has it's limits, because it might not pin-point just a single test in some cases, but instead should be easier to user interactively.

I think there were tests for this, weird that this typing change does not break any of them, maybe it's because of the way the array is expanded?

Yeah, casting a string-array to [string[][]] places each value in their own inner array. So when we looped this array and performed a string -like Array[1] match later the implicit cast back to string saved us. Pure luck 😄
