// we don't raise event concurrently
//
// we have this issue to track proper fix for preview 3 or later
// https://github.com/dotnet/roslyn/issues/32551
//
// issue we are working around is the fact this event can happen concurrently
// if RegisteryText happens and then UnregisterText happens in perfect timing,
// RegisterText got slightly delayed since it is async event, and UnregisterText happens
// at the same time since it is a synchronous event, and they my happens in 2 different threads,
// cause this event to be raised concurrently.
// that can cause some listener to mess up its internal state like the issue linked above
