// This is only a problem for the *second* (or third, forth, etc) instance of

// other instances have to create a new tracker...each time.
//
// Not an ideal solution, but basically we temporarily hold the printing to console
// for errors for which GUIUtility.ShouldRethrowException(e) returns false.
// The errors that may occur during this brief "bad state" are SerializedProperty
// errors. If the custom Editor created and remembered references to some
// SerializedProperties during its OnEnable(), those references will be invalid
// when the tracker is refreshed, until this GUIHandler is reassigned. This fix
// just ignores those errors.
//
// We don't simply early return here because that can break some tests that
// rely heavily on yields and timing of UI redraws. Yes..
