Typo: Return promise vs resolve promise

[joeyparrish]

I believe here:

picture-in-picture/index.bs

Line 353 in 8e59095

4. Return |promise| with the <a>Picture-in-Picture window</a> associated with

Return promise ...

Should say:

Resolve promise ...

[marcoscaceres]

Agree. Further, retuning the promise should be step 1, then go in parallel, then eventually queue a task to resolve it.

Thanks @joeyparrish for catching this!
I've opened #227 to address this issue.

@marcoscaceres The first sentence says The {{requestPictureInPicture()}} method, when invoked, MUST return <a>a new promise</a> |promise| and run the following steps <a>in parallel</a>: which I believe should be enough.
