The decorator.sequencer testcase fails intermittently

[yurivict]

It succeeds most of the time, but sometimes it fails like this:

Thanks for reporting! This suite tests an already deprecated feature that we'll remove in the next release, so it's not really worth the time to hunt down whether it's an issue with the test itself or an actual issue with the decorator. I'll just remove the test suite ahead of time.

@Neverlord

How can this code be tested then?

[Neverlord]

What do you mean? The sequencer code won't change since we will drop it soon, so we don't need regression tests in place.
