Review Comment:
   Logically if `hasRichFunction == false`, we will never access the value of 
`broadcastVariablesReady`. So it seems unnecessary to set the value here.
   
   But thanks for the catch, I found it unnecessary to call this function here 
since it is always initialized in `RichContext`. 
   
   I will remove these three lines later.
