<pre>Modern IDB: Prevent the same transaction from being commited/aborted twice
Rarely, due to page navigation or worker shutdown, a transaction might be either committed or aborted after it has already been committed or aborted.
I could not reproduce this with a targeted test case attempting to reproduce it, but it is showing up as a source of at least some of the mysterious flakes (<a class="bz_bug_link

By detecting this situation and turning it into an explicit error, we'll turn at least some mysterious timeouts into errors that will then become more actionable.</pre>
