.anyOf query return is inconsistent but .bulkGet works

[frankleng]

is there any difference in the concurrency logic for bulkGet and where('id').anyOf([...])?

it seems like anyOf has some sort of debounce that suffers from a race condition.
if we call .anyOf rapidly the final result may not be current. it works if we add a short delay between each call.

.bulkGet does not suffer from this, but I'd like to use anyOf so we can sort

anyOf uses an IDBCursor to iterate results sequencially in index order while bulkGet executes multiple calls to IDBObjectStore.get() in parallel.

AnyOf has been almost untouched for 8 years. There have been shaky bugs in the Safari implementation of IDBCursor historically but for the last 3-4 years or so, I haven't heard of any race-condition bugs in IDBCursor particularly.

Would it be possible to create a reproduction of the issue in jsfiddle or similar? That would help a lot.
