This works as expected. It's because element.innerHTML = 'string with your script tag...', which is used under the hood, does not execute scripts due to security reasons. See this stackoverflow post to learn more and for ways to work around it

I'm well aware of that SO post, but it doesn't help in any way when you use innerHTML under the hood (which I cannot modify). Nevertheless I acknowledge the resolution of this issue is wont fix.

Yes, it's won't fix for the same security reasons - we can't just patch over the underlying browser behavior here, that would potentially be very unsafe for other apps.
