Respect the source rectangle when drawing a canvas to another canvas.
This allows us to run the three.js examples without panicking, since they use self-drawing canvases to scroll the FPS graph.

Though I think it may be slightly fishy if used in, e.g., a @keyframes block.
For our purposes right now it doesn't make a difference, I think.
Bug: 1466008
MozReview-Commit-ID: A7VCTOqaIuB
Currently, NAC always inherits from the closest non-NAC ancestor element,
regardless of whether it is for an element-backed pseudo or not.
This patch changes the inheritance so that for element-backed pseudos, we
inherit from the closest native anonymous root's parent, and for other NAC we
inherit from the parent.
This prevents the following two issues and allows us to remove the
NODE_IS_NATIVE_ANONYMOUS flag:
* Avoiding inheriting from the non-NAC ancestor in XBL bindings bound to NAC.
- This is no longer a problem since we apply the rule only if we're a
pseudo-element, and all pseudo-elements are in native anonymous subtrees.
- This also allows to remove the hack that propagates the
NODE_IS_NATIVE_ANONYMOUS flag from the ::cue pseudo-element from
BindToTree.
* Inheriting from the wrong thing if we're a nested NAC subtree.
- We no longer look past our NAC subtree, with the exception of
::-moz-number-text's pseudo-elements, for which we do want to propagate
::placeholder to.
A few rules from forms.css have been modified because they're useless or needed
to propagate stuff to the anonymous form control in input[type="number"] which
previously inherited from the input itself.

fix logic in overflow_direction, also add a FIXME
<!-- Please describe your changes on the following line: -->
This PR fix#19477, which the logic is obviously wrong.
However, it is impossible to add a test for this.
Due to #20867, the ` overflow_direction` is a hard code now. It never go to other conditions.
I add a FIXME there, and also add a SPEC link.
