Re: Proposal: will-animate property

Alright I'd like to reach an consensus on how to best handle stacking
context issues since so far there doesn't seem to have one yet.

Currently forcing a stack context for all usage of will-animate is better
for forward compatibility. For example 'will-animate: new-prop' would have
the same rendering for any browsers that supports it. It was said above
that forcing a stacking context isn't necessary to optimize the content by
layerizing under certain conditions. Not forcing a layer is handy for
authors where one wouldn't be otherwise required.

Do any other CSS property have the property that whether they force a
stacking context depends on their value? It might be confusing to authors
that will-animate may or may not force a stacking context.

Thoughts?
