any idea if WebComponentsReady works? it's a shame to need a delay

I believe that WebComponentsReady is only in the CustomElement polyfill. And I'm
not convinced that's what the issue is.

does 0 work? I worry a number like 50ms is going to be flaky for timing issues

Yeah, should be zero. Was hoping 50 would help with IE, but no difference.
