The reverted commit pinned the plugin version on stable because the changes in that commit aren't compatible with stable. However, the version that we pinned the plugin to has a bug on stable and 50e62d84e8 fixes that bug. So we need to temporarily revert 5e24556b24 to unpin the plugin and I'll create another PR to undo this revert and re-pin the plugin version to this commit for sites on stable.
