Cypress v3.3.0 hangs

Current behavior:

After upgrading to Cypress v3.3.0, I’m experiencing hanging tests, similar to the ones described in https://github.com/cypress-io/cypress/issues/1235 and https://github.com/cypress-io/cypress/issues/1333. The DEBUG=cypress:* logs continuously show the following logs once it hangs:

Desired behavior:

Tests shouldn’t hang and all tests should pass. Desired behavior is restored when I revert to Cypress v3.2.0

Steps to reproduce: (app code and test code)

Unfortunately I don’t have a chance right now to try and set up a reproducible example. However, v3.3.0 consistently hangs, and v3.2.0 consistently passes.

Versions

Cypress: 3.3.0 Browser: Electron 61

My tests are also hanging in CI, but I’m not using video or iframes.

The original issue of seeing this warning in the console has been fixed since Cypress 3.5.0 when we updated Electron as part of https://github.com/cypress-io/cypress/pull/4720

Error while parsing the 'allow' attribute: 'accelerometer;', 'autoplay;', 'encrypted-media;', 'gyroscope;', 'picture-in-picture' are invalid feature names.

Closing as resolved.
