Bug 40112 and r64537 introduced ActiveDOMCallback which can be suspended & resumed when needed.

However it doesn't cover JSCustomVoidCallback which is used by database transaction as success callback.

This results in:

1) the callback can be executed when page loading is deferred (for example, when a JS dialog shows up). I've verified this with Google Chrome.
2) the original issue of Bug 40112 could still exist for success callbacks with real(non-null) transactions. I haven't verified that though.

My patch for https://bugs.webkit.org/show_bug.cgi?id=49401 was rolled out otherwise 1) wouldn't be an issue.
