Josh, could you take a look at this?
Vsevik, could you review this?

This fixes the assert I get when running with epg's idb directory in a debug build of chrome.

After I fixed that I noticed that the inspector was printing errors:
[22373:22373:1015/141603:ERROR:CONSOLE(828)] "Uncaught TypeError: Cannot read property 'databaseId' of undefined", source: chrome-devtools://devtools/devtools.html?docked=true&dockSide=bottom&toolbarColor=rgba(242,241,240,1)&textColor=rgba(76,76,76,1) (828)


The js change stops those from spewing but I don't how this._database isn't initialized before the call to select.

LGTM.

But since IDB is async and this._database is populated in update() in response to _indexedDBLoaded() firing, perhaps the selection can be set earlier programmatically?

(This is really a question for the Inspector folks.)

This is just hiding the manifestation of the problem without fixing it. Please revert before landing.

I filed https://bugs.webkit.org/show_bug.cgi?id=99434 for that issue, I can fix it myself.
