* mark string as html safe before passing to translation instead of bypassing HTML escape using {{{unsafe}}} syntax
* replace ember-i18n with ember-intl
All CI tests currently run in TravisCI are ported to GitHub Actions except for the BrowserStack tests.
TravisCI is kept in place for some transition period until we know GitHub Actions are working as expected. Also tests run on BrowserStack must be migrated to GitHub Actions before.
* upgrade Ember CLI to 3.13 and Ember Source + Ember Data to 3.12
Ember Source upgrade to 3.13 is blocked by Ember CP Validations,
which does not support Ember Source 3.13 yet.
Ember Data upgrade to 3.13 is blocked by Ember Data Model Fragments,
which does not support Ember Data 3.13 yet.
Also removes autofocus mixin and inlines the code as mixins are
considered an antipattern in latest Ember versions.
Removes some left overs in `"resolutions"` key. But that shouldn't have a real impact.
Drops ember-radio-buttons addon and uses a plain input element instead. ember-radio-buttons doesn't seem to be maintained anymore and required jQuery. Also plain input element seems to be much easier to maintain.
Replaces ember-ajax by ember-fetch as ember-ajax is build on top of jQuery.ajax().
This reduces the bundle size by 25 KB (JavaScript) after gzip. Updating the size limit accordingly.
- 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.
Use test helpers provided by ember-cli-clipboard as they do not trigger confirmation in IE 11. Upgrades ember-cli-clipboard to latest version as the outdated version used before does not include these test helpers yet.
Also refactors test execution against BrowserStack to only run tests one by one. Not quite sure why but that fixes the IE 11 issue. Need to investigate later as that one slows down tests by requiring two additional builds.
