I was investigating the weird CI failures in #15839. Long story short the CI failure is caused by the same issue in #15896 where
RunTask
events can sometimes be overlapping.We fixed this when calculating observed TBT in #15921, but we did not correct the overlapping tasks in Lantern.
I suspect we may need another PR to address this in
main-thread-tasks.js
as well...
