It is unclear if this will help reduce flakiness and timeouts. Until now
the test was setting the listener and making the transition on the same
microtask. If the transition were to complete before the listener is
fully set up, then that would explain the timeout: the transition event
is never fired at that point. Honestly, I find this scenario hard to
believe, but regardless it is worth a try.
This small refactor changes the order to ensure the listener is set up
upfront, and only later we initiate the transition.
