First use of wrapped field shows an empty help bubble

[jfengel]

This is visible in the ContextHelp demo:

Click on "Wrapped fields"
Click on a ?

(Image upload isn't working. What I see is an empty help bubble, in the top-left corner of the screen.)

I also get a stack trace:

After you use F1 to bring help, subsequent requests work. I've observed this on Firefox and Chrome.

Thanks for the report, I've been able to reproduce this.
