Provide/Inject fails with polyfilled Symbol

[privatenumber]

Version

2.5.12

Reproduction link

https://jsfiddle.net/hirokiosame/dronjdzm/16/

Steps to reproduce

Run code in IE11.

Either remove the <wrapper> from the Parent component on L25 or change the Symbol into a String on L9 and it will work fine.

What is expected?

For it to print "Message from parent: Hello World from Parent"

What is actually happening?

Doesn't receive the injection.

Symbol isn't even supported in IE11. Are you using a polyfill?

Yeah, checkout the External Resources section; it's using babel-polyfill 6.26.0

I'm hesitant to say that it's an issue with the Symbol polyfill specifically since it works when I change the <wrapper> in the Parent component on L25 to a <div>.

I've found that the bug is only reproducible:

1. when the symbol is converted into a string
2. when the Parent is not using a wrapper component that is also providing arbitrary data.
