Expected behavior

Run https://github.com/getgauge-examples/js-taiko specs in parallel on Mac without error

Actual behavior

Steps timeout.

Tried multiple things like downgrading, upgrading chromium version and other dependencies. Launching chromium with suggested command line args and increasing max memory using --max_old_space_size=4096 but nothing seems to help.

seems to happen when run serially sometimes too https://build.gauge.org/go/pipelines/Taiko/442/functional-tests/4, one thing which was causing flakiness was the size of iframes in the test, since it was very small page's scrollHeight became long causing firstMeaningfulPaint event to get triggered after a long time. Updating the size helped to minimise the flakiness, still seems to happen occasionally. Suspected mac firewall, even turning it off dint affect it.

one observation is that the test suite works runs fine in parallel when run in headful mode but times out when run in headless mode. Need to investigate if its an upstream bug

Works fine with fix ef48f7b
