next (error | completed)?
This behavior breaks the grammar because there is overlapping between sequence events.
Observable sequence is trying to send an event before sending of previous event has finished.
> Interpretation: This could mean that there is some kind of unexpected cyclic dependency in your code,
or that the system is not behaving in the expected way.
> Remedy: If this is the expected behavior this message can be suppressed by adding
or by enqueing sequence events in some other way.
