Cypress: Ajax Synchronous Request Failing in Chrome

[Premm]

Is this a Feature or Bug?

Bug

Current behavior:

I am getting the error

Error: NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load '_url_ ': Synchronous XHR in page dismissal.

when using Chrome 73. If I switch to Electron 59 everything passes fine.

Desired behavior:

To not get this error in Chrome 73.

Steps to reproduce: (app code and test code)

Not exactly sure how to reproduce this issue but i believe it's caused by an update to chrome that disallows synchronous ajax during end-of-page events (like beforeunload and unload). It's not mentioned in any release docs, but according to this stackoverflow response it was mentioned in a tweet somewhere. From experience, it happens when an ajax request is made in a test, and then is shown as aborted in the following test. Sorry if this issue wasn't detailed enough.

Versions

Cypress 3.2.0, Chrome Version 73.0.3683.103, Windows 10

Never mind. I believe Cypress is actually working correctly and failing on a request that as of chrome v73 should not be happening. The request is made by a 3rd party tool which still appears to be using synchronous xhr requests in the beforeunload/unload events.
