Café expresso congelando em exibição com loop de animação

Eu tenho uma visão na qual um elemento é animado com o seguinte em um loop infinito:

<translate
    android:fromXDelta="0%"
    android:toXDelta="100%"
    android:duration="10000"
    android:repeatCount="-1"
    android:repeatMode="reverse"/>

Quando o Espresso abre minha atividade, ele pode executar algumas operações, mas congela rapidamente. Suponho que o Espresso esteja aguardando o thread da interface do usuário ficar ocioso, o que nunca acontece neste caso.

É a única maneira de testar essa visão para implementar um mecanismo para desativar animações? Eu poderia ter outra classe para lidar com animações, que seriam ridicularizadas para testes. Ou crie condicionais de tempo.

Editar: ainda não criei um projeto de amostra para tentar recriar o problema, mas aqui estão alguns detalhes adicionais:

1) Estou usando o Jake WhartonActivityRule para que minha atividade seja iniciada automaticamente (https://gist.github.com/JakeWharton/1c2f2cadab2ddd97f9fb)

2) Este é o meu teste:

onView(withId(R.id.btn_yes)).perform(click());

3) Aqui está o rastreamento completo da pilha. Note oAppNotIdleException:

4) Rastreia a pilha ao pausar a execução do teste enquanto está congelado:
