Current behavior:
Running tests hangs.
With cypress run, it times out having never begun the first test.

With cypress open, the Test Runner browser opens, but the test doesn't start running for 30+ minutes. It appears blank.

The culprit seems to be this line. Surrounding it with console.time/timeEnd results in it taking over 30 minutes to run.
Test code to reproduce
This can be seen in the Cypress Dashboard internal tests. Still trying to narrow it down to an easily reproducible (and publicly-postable) case.
Versions
Cypress 4.6.0
Current Workaround
Downgrade to Cypress 4.5.0.
