Thank you pointing out this issue and thank you for your effort of actually diving into the source code and finding the location of the culprit. It looks indeed like the line setTimeout(run, request.retryWait); removed in this commit is the problem. It seems to be responsible for whenever the attempted request fails not due to the server, but due to a genuine network fail (e.g. network timeout) and the browser does not receive any kind of response, this leads to the described issue. Requests that fail on the server and return some kind of status code =! 200 are still handled correctly because the function xhr.onload has an setTimeout(run, request.retryWait);. I likely moved the line from the handleErrorAndRetry function into xhr.onload and forgot about xhr.ontimeout and xhr.onerror functions. Again, thank you for finding this!

It shouldn't be too difficult to fix. Do you want to create a Pull Request? I can then create a new release.
