Drop support for IE

Most tech companies (LinkedIn, Zendesk, etc) has already dropped support for IE11.

Microsoft themselves will drop support in August (https://www.theverge.com/2020/8/17/21372487/microsoft-internet-explorer-11-support-end-365-legacy-edge).

Maybe this repo could drop support for IE?

Support would still be available in earlier versions, so anyone who still need it can just pin their version and not upgrade.

I'm guessing it would allow for dropping a bunch of work-arounds and IE specific stuff + enable use of some modern web APIs.

Thanks for the suggestion. There isn't all that much logic in the library to continue supporting older IE versions. It mostly boils down to supporting the lack of classList, some quirks around event properties (such as button/buttons), and the older PointerEvents implementation.

When these considerations start being a problem, I'd consider dropping support for older browsers. For now, I'm not planning to actively remove support, since the impact is so minor.
