How would the browser distinguish between

storage-operation-1
inadvertent-API-call
storage-operation-2-that-should-be-atomic-with-1

and

storage-operation-1
API-calls-to-gather-data-for-another-transaction
storage-operation-2-that-is-unrelated-to-1

?  Seems like that's a necessary distinction if it's not to just warn
all over the place uselessly!
