Recent change to createSocketURL.js causing error in IE11

[akolssontd]

I'm getting the following error in IE11: Object doesn't support property or method 'endsWith'

It appears to be caused by a recent (3/18/2022) change in createSocketURL.js where

if (protocol && protocol.substr(-1) !== ":") {
    protocol += ":";
}

was changed to

if (protocol && !protocol.endsWith(":")) {
    protocol += ":";
}

I've tried to add a polyfill for "endsWith", but it doesn't appear to work. Perhaps I'm not adding it in the right place (index.js of my React application).

Does anyone know where I should be adding the polyfill or is there a way to prevent the code in question from being included in my dev build?
