Behaviours hide field support for bundled fields from 'Extension for Jira Service Desk'

As a user,

The app allows me to create bundle field which comprise a 'bundle' of other fields of varying types.

Behaviours' hide field switch should work as expected on the bundle field. 

It takes a variable amount of time for the Bundle Field to be generated and rendered on the page, and if it takes too long, ScriptRunner fails to hide it.
