This is the primary change in this PR: the new beta (which has been untouched for a year as of writing) actually does a better job of handling concurrent read receipts, this patching holes. The beta doesn't have the same leak as v1, so we can remove the metadata hack from our side (it doesn't use jQuery's data anymore). Note that this change on its own introduces an annoying bug where every second update to a read receipt will throw it 14px to the right - more on that in the next commit.
