Jonathan Gamble d065f6bf00 LibWeb: Perform a microtask checkpoint - VERIFY after reentrancy return ...

The HTML event loop spec explicitly provides guidance for reentrancy in
the "perform a microtask checkpoint" algorithm, so we cannot VERIFY
for empty execution context before this early exit (as much as we'd
like to).

https://html.spec.whatwg.org/multipage/webappapis.html#perform-a-microtask-checkpoint

See the microtask-checkpoint-reentrancy-via-responsexml-script test for
an example of how this can happen from user scripts.
