Steps to Reproduce

Execute toJSON on any realm Object using release 10.6.0.

Code Sample

var newmsg = draft.toJSON();

Probable Cause

File realm\lib\extensions.js was modified in version 10.6.0.
In line 112, a new comparsion was added. But realmConstructor.Dictionary is undefined.
Therefore, instanceof throws an exception.

Version of Realm and Tooling

• Realm JS SDK Version: 10.6.0
• Node or React Native: React Native
• Client OS & Version: Android 10
• Which debugger for React Native: Chrome debugger
