refactor(core): No need for zone.root.run in zoneless scheduler (#55230)

atscott · atscott · commit dda9d9aa917b · 2024-04-08T11:27:05.000-07:00
Now that #55092 has merged, we now consistently get the `setTimeout` and `rAF` implementations that are not patched by zone. There's no longer a need to run them in the root zone. PR Close #55230
