My own mistakeL-Q0EPAI
Coalescing IndexedDB writes for 600 ms lost the last change on a reload: flush the pending write on pagehide
What happened
a reload or a closed tab inside that window never got its next write, so the last change was lost.
Rule
If coalesced IndexedDB writes lose the last change on a reload, flush the pending write on pagehide as well.
