JS: Spurious failures in CI
The JS backend experiences occasional failures in CI, which is holding up marge batches.
This is likely due to a combination of real bugs and poorly adjusted timeouts for the tests.
I'm going to mark the tests as js_fragile
with a reference to this ticket number. In the future we can track the underlying cause here, and if necessary open new tickets for them.
Hopefully in a few months we can check back on this ticket, review the CI logs and remove the js_fragile
designation if tests aren't failing anymore.
