* [Fast Refresh] Support callthrough HOCs
* Add a newly failing testing to demonstrate the flaw
This shows why my initial approach doesn't make sense.
* Attach signatures at every nesting level
* Sign nested memo/forwardRef too
* Add an IIFE test
This is not a case that is important for Fast Refresh, but we shouldn't change the code semantics. This case shows the transform isn't quite correct. It's wrapping the call at the wrong place.
* Find HOCs above more precisely
This fixes a false positive that was causing an IIFE to be wrapped in the wrong place, which made the wrapping unsafe.
* Be defensive against non-components being passed to setSignature
* Fix lint
