Finalazier thread is blocked becasue of JavaScriptEngineSwitcher.ChakraCore.ChakraCoreJsEngine #34

Hi, @Taritsyn! First of all thanks for your great work on this project!
We use JavaScriptEngineSwitcher.ChakraCore 2.3.2 with ReactJS.NET. But from time to time we are facing the issue that our azure web app crashes and doesn't response. After looking into memory dump I've found that the reason of that is that finalizer thread is blocked. It becomes blocked after trying to finalize ChakraCoreJsEngine.
According to version history I found that similar issue was fixed in 2.3.2 version but looks like not completely. Could you please help with fixing this issue?
Maybe something is going wrong because of using reference type objects in Finalize method.
I attached a stack trace below.
