Simon Holthausen	7109d19734	fix: remove scheduled roots invariant ... Working on adjacent issues, two things became apparent: - the way we check if the microtask in `ensure` is outdated is wrong. `current_batch` could be `null` for other reasons. Instead check if it's still alive. - the "batch has scheduled roots" invariant is wrong: you can end up with scheduled roots if you have multiple batches that are scheduled to be resolved in the same microtask. This can happen like this: first batch goes into queue, does `queue_microtask`, another microtask that was scheduled earlier resolves, this one also schedules a batch, which does not do `queue_microtask` (because we queued one already) and instead just adds another entry to the list of tasks. Then two batches are in the task queue, and if the first commits it might try to rebase the second one, which is scheduled to flush directly afterwards, and then the invariant check wrongfully crashes the process.
