Karma 6.x fails to load in IE9

See original GitHub issue

Updating from karma 5.2.3 to 6.2.0 I find that the tests no longer load in IE9, for example via SauceLabs on the https://github.com/js-reporters/js-reporters repository:

In the video recording, I see that the “Karma is Idle” page appears but nothing after that. No further error what I could find, so probably something very early on. Perhaps something with socket.io, or unsupported ES6+ syntax or method in client changes?

I’ve just tried to run tests on IE9 and apparently they pass: https://automate.browserstack.com/dashboard/v2/builds/353284844776d04545344febcc9ac02d87a7b113/sessions/754cc7a656eadfaf9abc8d7462d2724bbb793a07?buildStatuses=running&buildUserIds=3623869 (requires auth). The problem is that on initial page load the page does not connect back to the Karma server, but after reload it successfully connects and tests pass. I have no idea why this happens. I’ll try to poke around more in the coming days.
