Steps to reproduce the problem:
Test the EXAMPLE codes on specification.

for example 'BitCrusher' EXAMPLE 16,
there is no process() return value and says

   // No need to return a value; this node’s lifetime is dependent only on its
   // input connections.

but it will not work without 'return true;'

What is the expected behavior?
Nodes that transform their inputs, and are active only while connected inputs and/or script references exist. Such nodes SHOULD return false from process() which allows the presence or absence of connected inputs to determine whether active processing occurs.

What went wrong?
However, in the implementation, even if the input is connected, returning false stops the node.

Did this work before? N/A 

Does this work in other browsers? N/A
