Going back to the check for this.props.forwardRef used in #6261 (comment) "fixes" it, which indicates the ref forwarding isn't working or as @aduth mentioned in Slack might not be working when no refs are assigned to be forwarded...

Ya the issue here is that there is probably something else using withGlobalEvents that is not setting a ref which gets forwarded. So there must be a check to see if there is a forwarded ref before acting on it. Definitely the solution is to add back in the if ( this.props.forwardedRef ) check in handleRef.

Yeah after running through the code that still seems to be the best option, and I can't see it breaking anything. Patch incoming...
