Another option would be to throw an error for this case, what do you think? Do we need to dig deeper into why maxDependencyEndTime is greater than lcpTimingsAfter.endTime?

Let's not throw an error, but I don't think this PR should close #16261
Also could we do something like wastedMs = Math.max(wastedMs, 0) on the line below this. I think that would make this easier to read.

I don't like this sort of fix because it covers up this and future problems. I suggest not doing this, but defer to @adamraine |
