- the billing modal is always rendered, it's contents being shown/hidden via CSS
- when the billing modal was rendered it was changing the `key` scope and binding the enter key, however because it's always rendered this was messing with the default key scope for all other areas of the app
- removed all keyboard handling from the billing modal because it wasn't actually doing anything (there is nothing to handle the "confirm" action when Enter is pressed) which fixes the unexpected key scope change
no issue
The billing iFrame needs to be rendered within the `main` content area rather than as fullscreen.
This needs most probably more tidying up, but is working for now without breaking the functionality.
* Move billing iFrame to render in main content area
* Fixed routing error when transistion url not defined
* Removed close modal button and esc key binding
no issue
- Opted in to use explicit `hisotry.replaceState` and setting iframe's `src` using assignment instead of tracking it through computed property. This allows for tighter control over when iframe's history is updated which was causing problems when `src` was bound to computed property
- Added billing page metadata. This way browser history records appear with nicer signature
- Removed "update button" iframe and rewrote "global iframe" to not use modals. This allows to have single iframe on a page, which simplifies `postMessage` communication and preserve history inside iframe to be able to navigate it after closure
- Added route change handler responding to BMA app route changes. Allows to sync browser URL visible to the user with active route in BMA iframe. The sync is based on `hisory.replaceState` method that makes sure singular history records are kept in the browser history
- Added nested wildcard billing route. This is meant to catch all the nested routes inside of BMA iframe
