It looks like the FetchReadableStream is released on the unexpected thread.
According to the stack, the release is triggered by WorkerPrivate::MaybeWrapAsWorkerRunnable and dispatched to the worker thread. However, it has no enough information to tell where the FetchStreamReader was created.
Is this related to PFetch? Currently, I will say it seems not. As I know that PFetch creates the fetch response on the worker thread. If the response's readable stream is also released on the worker thread, it should be no problem since everything is on the worker thread.
To debug this assertion, we need to know where the FetchStreamReader is created.

Now I am more confident this is not a regression of PFetch since we had haven some reports before PFetch landed. See bug 1777106 and bug 1802116.

Hi Edgul. Bug 1777106 and bug 1802116 reported the same crash stack. Should we set this bug and bug 1802116 as duplicates of bug 1777106?

Since the crash volume is low (less than 15 per week), the severity is downgraded to S3
. Feel free to change it back if you think the bug is still critical.
For more information, please visit auto_nag documentation.
