AsyncReactiveProperty.WaitAsync() doesn't trigger under certain circumstances

[faveris]

I've found a case when AsyncReactiveProperty.WaitAsync() doesn't trigger: code is not passing "await" line despite the property value has changed. This is a rare case, but it reproduces for 100% of tries if requirements are met. I've attached a sample Unity project, to reproduce the issue you need to:

1. Open AsyncPropertyTestScene.unity
2. Enter play mode
3. Check the console - two listeners are triggered the first time value has changed and only one listener is triggered the second time

Sample project: AsyncPropertyTest.zip
