Do we have enough coverage around this? Can we maybe add a few Unit/Integration tests? It'd be good to see if we can repro the behavior seen in the linked ticket without this fix and show that it's no longer an issue with this patch.

It looks like the right thing to do but I'm not sure if we'll end up uncovering some other subtle bug by changing this order.

I want to try to add tests around this I just am not sure I will be able to the unit test it, fakeclient is not accurate enough for unit tests to work possibly, and I am worried about how to simulate it in e2e but I plan on trying both especially if I can get some confirmation that it does in deed seem to fix the issue. I agree though that getting a reproducible test would be ideal. I did hack together some code to test this locally but it involved editing rollouts controller to do a double update.
