* Adds a loading spinner to form buttons as long as submission is pending.
* Does some refactoring of form navigation buttons.
* Updates expected bundle size.
- Drops floatthead and additional scrollbar
- Makes header and first column sticky
- Refactors code for readability
Sticky header is only working in Firefox. Chrome and Edge does not support `position: sticky` for `<thead>`. Haven't tested Safari.
This also fix a bug if user creates more than one croodle without reloading window
in between. In that case a data fragment is reused which throws.
It's also the first step in dropping {{simple-select}} which is very outdated.
Ember Bootstrap has changed a lot since the very outdated pre 1.0 release
which was used here. Changes are mostly about using composable components
and closure actions.
Also replaces PhantomJS with Chrome in CI cause PhantomJS is also very
outdated and causing test failure not related to any real world issues.
Ember CLI has replaced PhantomJS with Chrome in v2.15.1, which is the
upfollowing minor release to the version currently used.
Ember.ObjectController was proxying model properties to controller. Ember.Controller which should be used is not.
Therefore we have to define if it's a property of controller or model.
Also added two more tests:
* anonymous participation
* do not force an answer for all options
