This reverts commit ec22840c4a.
This patch currently creates issues on beta, which still runs with the
latest vendor version of Parsoid. If, for some reason, Parsoid doesn't
get deployed with this patch, I2acfd0b7a1e48aec107ded3bbe4963e2df24f4d3
doesn't get included, and the REST page handler breaks.
Staggered deploy seems safer in this context, hence the proposal for a
temporary revert, and a merge after the next Parsoid vendor patch is
deployed.
