Hello :wave:
Any ideas what might be causing the flakiness of SpringBoot websocket integration tests -&gt; <https://github.com/ExpediaGroup/graphql-kotlin/blob/master/examples/server/spring-server/src/test/kotlin/com/expediagroup/graphql/examples/server/spring/subscriptions/SimpleSubscriptionIT.kt|https://github.com/ExpediaGroup/graphql-kotlin/blob/master/examples/server/spring-[…]ql/examples/server/spring/subscriptions/SimpleSubscriptionIT.kt>

Locally it always works fine but when run GH actions one of the tests randomly fail (after updating to SpringBoot 2.4.2 they fail much more often) with race condition - generally skipping the first message from a stream

`.subscribe()` doesn’t block. `.block()` does. My guess is this is what’s causing the flakiness.
