I'm assuming this Mac OS test is flaky since it timed out - could someone rerun that one if needed? |

We're guaranteed this runs before any userland code right?
(Just making sure this is safe since it's weird we set up Symbol.dispose here (if someone tampered with symbol they can set up a getter that throws here) but we use ObjectDefineProperty which is a primordial that guards against this sort of tampering))

I’m assuming that the file called “pre execution” runs before any userland code - if not, this polyfill is highly problematic conceptually :-)

Are these 3 failing tests something I need to address? |
seems like a fluke, I reran the tests |
|
@MoLow still failing; are they flaky or do i need to look into it? |
passed now |

This commit does not land cleanly on |

added
the
backport-requested-v18.x
|
@ruyadorno node 18 doesn't seem to have Symbol.dispose polyfilled, so i think this PR should have "do not backport" to <= 18? |
|
node 18.18 was released today with the symbols, so maybe? |
|
oof, ok then perhaps it will indeed backport cleanly into 18.18 :-) |

Happy to add a test if needed - but I both wasn't sure where it would go, and I also wasn't sure if this was worth testing since node rarely polyfills JS builtins and v8 will supply it soon enough anyways (backed by test262)
