π Description
This PR fixes an bug where setting a token value from a subscriber causes a RangeError, max call stack exceeded.
π« Issues
Closes #6464
π©βπ» Reviewer Notes
The core of the issue is that setting a token from a subscriber would force DesignToken to go through the notification code-path again. Because the subscribers had not been cleared at that point, it would enter an endless loop and throw. To avoid this, the notification stack is cleared before any of the notifiers are called. This avoids the recursive loop and the scenario no longer throws.
