Radios can be associated with a 'conditionally revealed' content block – for example, a radio for 'Phone' could reveal an additional form field for the user to enter their phone number.
These associations are made using a data-aria-controls attribute, which
is promoted to an aria-controls attribute during initialisation.
We also need to restore the state of any conditional reveals on the page (for example if the user has navigated back), and set up event handlers to keep the reveal in sync with the radio state.
HTML element to use for radios
Private$inputsPrivate$moduleStaticmoduleName for the component used when initialising using data-module attributes.
PrivatehandlePrivateClick event handler
Handle a click within the $module – if the click occurred on a radio, sync the state of the conditional reveal for all radio buttons in the same form with the same name (because checking one radio could have un-checked a radio in another $module)
