- [X] `./mach build -d` does not report any errors - [X] `./mach test-tidy` does not report any errors - [X] These changes fix #18286 and #18308 This patch makes the Performance Timeline API work in workers, removes the exposure of `Performance.timing` in workers and sets the appropriate value of `Performance.now()` in workers.
