Photon Realtime, StripKeysWithNullValues cause heavy GC Alloc


In our current project, we use Photon room properties to sync entities. and i noticed some heavy GC Allocs while deep profiling the game and it always ends down to this method.

enter image description here

Have anyone faced this issue before ? or attempted to fix it ? here is the source code of that method.

/// <summary>         /// This removes all key-value pairs that have a null-reference as value.         /// Photon properties are removed by setting their value to null.         /// Changes the original passed IDictionary!         /// </summary>         /// <param name="original">The IDictionary to strip of keys with null-values.</param>         public static void StripKeysWithNullValues(this IDictionary original)         {             object[] keys = new object[original.Count];             original.Keys.CopyTo(keys, 0);              for (int index = 0; index < keys.Length; index++)             {                 var key = keys[index];                 if (original[key] == null)                 {                     original.Remove(key);                 }             }         }
