no issue
- moved `@onLoad` trigger from `load` event to the `makeVisible()` task so that consumer code isn't called before load has fully finished
- fixes issue with portal sometimes not being ready when we perform the resize on the membership screen
- added guid as a cache-busting `?v={guid}` query param
- fixes issue where preview iframe can load stale data after a settings change resulting in a blank preview after going from "nobody" to "invite/anybody" because the loaded homepage is stale and doesn't have the portal script injected
