 > With this patch, an InvalidState error is no longer logged during
 browser startup. We still see one when we open the developer tools
 (Inspect Element). I don't know how difficult it would be to patch the
 underlying devtools/shared/async-storage.js code to avoid using IndexedDB
 when it has been disabled.

 Thanks for the review. That's a good suggestion. I wrote an in-memory
 implementation that is supposed to match the indexeedDB-based version:

 This seems to correctly the browser console input history during a browser
 session. It also appears to eliminate the InvalidStateErrors both as a
 result of browser startup, entering things in the browser console, or
 using Inspect Element.
