Issue on `children` following `prevAll`

[EHadoux]

Following up on #1754 it looks like prevAll does something the rest doesn't.
I have:

1. .prevAll(sel1).children(sel2)
2. .prevAll(sel1).first().children(sel2)
3. .prevAll(sel1).last().children(sel2)

Both 2. and 3. act like they should. However given the documentation on children (the children of the first selected element) you would expect 1. to act like 2. but it does exactly act like 3.

Edit: tested on both RC9 and RC10

Thanks for flagging! I can confirm that the docs for children don't match the actual behavior. The actual implementation returns the children from every element in the selection.

Cool, thanks for confirming. What's the planned next step? Changing the doc or the implementation? I probably have a lot of calls to children where I didn't check the behaviour, so just for me to know if I need to put first everywhere or if it's gonna be fixed in a later version. Cheers!

We follow the jQuery API in cases like this. jQuery's docs point at the implemented behavior, so we'll update the docs: https://api.jquery.com/children/

Updated the docs. Thanks @EHadoux for the report!
