nit: Suggest "temporarily disable" in the CL description.

Given that we're reverting alpha shaping in CrOS, should we also revert the
window.setShape() API to be dev-channel only for now?

Not sure if APIs need to get rolled back to dev if problems are found while in
beta.

Ben, do we need to change the permissions to 'dev' or is it OK to leave it on
'beta'?
The SetShape API is functional before/after this change, but this cl disables
the alpha-channel clamping because it introduced a few bugs.
