Current Behavior 😯

Open https://material-ui.com/components/autocomplete/#virtualization in Internet Explorer 11 and open the dropdown. Then click the scrollbar and the dropdown will disappear.

Material-UI only partially supports IE 11 and doesn't intend to improve that. See Supported Platforms.

Overall, the library doesn't prioritize the support of IE 11 if it harms the most common use cases. For instance, we will close new issues opened about IE 11 and might not merge pull requests that improve IE 11 support.

As @michal-perlakowski mentioned, the opportunity cost is too high for us to work on IE 11.

Plus, this issue was fixed in v5, it's a duplicate of #22705.

@eps1lon The documentation in IE 11 is broken, it fails here:

https://github.com/mui-org/material-ui/blob/5a5348b7ee7726b3a542b496935363ee6df5845f/docs/packages/markdown/loader.js#L130

I would propose we don't fix it, so we don't get distracted by issues like this one. Hopefully, people will try the docs in IE 11, see that nothing works, and use a different library, or give up on IE 11.

Oh right, forgot to propose the change. Need to fix this anyway.
