      Description

      While running test/format configurated for backups with develop as of yesterday afternoon, changeset 070b5d8baa it immediately hit this assertion.

      __split_multi_inmem_final, 1560: upd != NULL && upd != supd->onpage_upd && supd->onpage_upd != NULL
      

      This feels similar to WT-5952, but I opened a new ticket since it is a different line and error message.

      Here's the stack:
