Testcafe: Testcafè hangs without errors when there is a temporary network disconnection

Bug

What is your Test Scenario?

The bug appears when launching the tests on a remote machine (Browserstack or similar, remote device) and a temporary network disconnection occurs.
We were able to replicate the issue on two machines in the same LAN using the code attached in the gist below.

What is the Current behavior?

When the network returns the tests won't continue, the browser is frozen and there are no error messages in the testcafè console.

What is the Expected behavior?

When the network returns, we expect the test to continue and either fail with an error, or better pass without errors.

How would you reproduce the current behavior (if this is a bug)?

You should run the attached html file on a local httpserver (we used the "http-server" npm module to achieve that), run the test file we provided with the remote option and disconnect the network for a while. See the other readme.md file in the attached gist for more information.

Provide the test code and the tested page URL (if applicable)

Thank you for the detailed description. I was able to reproduce the issue. This behavior seems incorrect. We need some time to research it. We will reply to you when we have news.
