Breaking error in IE 8

[ladas-larry]

How to replicate this issue

1. run Windows 7 with IE 8 on VirtualBox https://dev.windows.com/en-us/microsoft-edge/tools/vms/
2. clone this repo https://github.com/Dharmoslap/react-select
3. run "npm start" and open http://10.0.2.2 in IE 8
4. try to select different options and the error will appear

However it's not fancy at all, I still need to support IE 8 for a few more months.

Thanks

It seems to be React related issue, so I created the same one in React repository as well.

Do you know how to run unconcatenatded library inside your stack, to provide more information about the error?

Please see facebook/react#6291 (comment). It is not a React-related issue. IE8 doesn’t support isEqualNode() which is used in

react-select/src/Select.js

Line 313 in 18758f7

if (this.refs.menu && document.activeElement.isEqualNode(this.refs.menu)) {
