@x0day Thanks for the contribution. Looks like this was missed in the port.

Is this still an issue? I'm using 1.27.1.
If I add this to my code:
page.route(re.compile(r"(\.png$)|(\.jpg$)"), lambda route: route.abort())

I've verified images don't load which is desired but when the script finishes, I get a bunch of these:

Task was destroyed but it is pending!
task: <Task pending name='Task-666' coro=<Page._on_route() running at /home/username/.local/lib/python3.8/site-packages/playwright/_impl/_page.py:251> wait_for=<_GatheringFuture finished exception=CancelledError()>>
_GatheringFuture exception was never retrieved
future: <_GatheringFuture finished exception=CancelledError()>
asyncio.exceptions.CancelledError
