      Description

      We just keep the data size the same when we recover to a stable timestamp instead of correcting it like we do with counts: https://github.com/mongodb/mongo/blob/f757bc52b926943bc748f0dc33173ab16e980f61/src/mongo/db/repl/storage_interface_impl.cpp#L1025-L1028

      This means that the size reported in collStats will be wrong, it also can have the side effect of slowly decreasing the effective size of a capped collection, since the system will think it's more full than it actually is. Validate will fix the size.
