According to bug 1311466 comment 12: objectStore.getAll(), index.get(), index.getAll() and cursors
I also noticed this will fix an assertion failure in the hidden-by-default devtools Storage pane when attempting to explore an object store containing a wasm module.
*** Bug 1319693 has been marked as a duplicate of this bug. ***
tracking for 52 as that was requested in bug 1319693
Gentle ping about this: as stated in bug 1319693 comment 0, it's an easy way to crash the browser (especially since emscripten will try to cache wasm modules by default, iiuc): store a wasm module in idb, open devtools and look at the wasm module in idb.
Implementing the full feature might take some time, but maybe we can mitigate the crash in the time being in 52 (target for wasm release) by just failing softly?
(Oops, just noticed I forgot to CC relevant people on this initially.)
