There was a thread on this on the public webgl mailing list recently:
https://www.khronos.org/webgl/public-mailing-list/archives/1412/msg00062.html

Interestingly enough, I believe Safari and IE already avoid the problem
this would solve because they use the system compositor to composite there
layers instead of a built-in one.
