Remove session storage checks from accordion JavaScript #5044

Closed 36degrees closed 5 months ago

36degrees commented 5 months ago

We don’t do anything different if we detect the browser doesn’t support session storage, so we don’t really need to care whether it works or not.

We do need to wrap attempts to set or get from sessions storage in try blocks because setItem can throw QuotaExceededError exceptions and some older browsers will throw other exceptions if session storage isn’t available (disabled, or using private browsing)

However we don’t need to do anything different if exceptions are thrown – we can safely catch those exceptions and swallow them.
