Title: Fix #11230. .appendTo and pals should always stack.

The main case this affects is where there is only one target element. The result is the same element, it's just a stack of the same element. I believe this is the final case where we sometimes-stack based on the count of input parameters and/or connected-ness, unless you can find others. It's -30 gzip.

I think we need an explicit test for this, I'll create one before landing if it seems like the right way to go.
