Hello!

We occasionally encounter an issue where the NavHost randomly applies a default transition animation instead of the one specified for a particular composable/route. Please take a look at the sample project and screen recording I've attached. Even though composable<DefaultRoute> consistently defines slideInHorizontally/slideOutHorizontally transitions, you may sometimes observe a scale/fade animation instead. This bug is inconsistent and may require multiple attempts to reproduce. One observation is that this issue occurs more frequently when a new transition is requested just as the enter animation of a previous one is nearing completion.
