Ciao guys, I found a weird behavior with the conflate flow operator and throwables...
Basically, when throwing an exception from a flow that passes through a conflated operator, the re-thrown exception is different from the original one.
It's reproducible with the following code:

@Test
fun myTest() = runBlocking {
    val throwable = Throwable()
    try {
        flow<Unit> { throw throwable }.conflate().collect()
    } catch (caught: Throwable) {
        // We expect the same exception that we are throwing 
        assert(throwable === caught) { "Expected $throwable, found $caught" }
        // Prints "Expected java.lang.Throwable, found java.lang.Throwable"
    }
}

The same test without the .conflate operator passes.

Can you confirm that what I expect is the actual intended behavior and therefore this is a bug?
I'm on K 1.7.0 and coroutines 1.6.3
