This also needs to be wrapped in a Ref effect. Otherwise you might forget to schedule a Ref effect in the begin phase, but it sometimes works anyway accidentally because you happen to have another effect flag scheduled during the same commit.

Also I think this should be a regular else
block. Not else if
. Anything that's not manual should have its ref detached.

I don't follow this. What do you mean it needs to be wrapped in a Ref effect?

What if it switches from manual
to something else? We need to schedule a Ref effect to detach it. I think the test you wrote happens to work because it also schedules a Visibility effect during the same render.

I was playing around with this and couldn't come up with a test case to break this.
Anyway, I'm going to remove the condition to only call markRef if mode is manual.
