Robolectric tests froze forever after upgrade to 1.6.0, because of delay inside Dispatcher.IO

[neworld]

This code works totally fine on vanilla junit tests, or in <1.6.0 versions of coroutines, but it stuck forever in RobolectricTestRunner after upgrade to 1.6.0:

@Test
fun foo() = runBlocking {
    withContext(Dispatchers.IO) {
        println("before delay")
        delay(1000) // <------ here stuck forever
        println("after delay")
    }
}

Test dispatchers also work OK. Is it intended? If not, I can create a full project if it helps you to fix the bug. My case is similar to #1365

Could you try setting the kotlinx.coroutines.main.delay system property to false? This looks like an issue with the same root cause as #3173.

Thanks, @dkhalanskyjb. It works. I am closing this in favor of having one issue: #3173

This issue keeps popping up, I counted already five.
@qwwdfsad Maybe you can consider if anyhow possible to make a minor release where the delay change is reverted?
Last coroutines release was almost three month ago.
