Bugs Fixed
- Fixed regression in accessibility of headers
Implemented Enhancements
- Refactored header code to simplify code and make it easier to extend.
Breaking Changes
- `domestic_header_static.html` has been removed. I believe this is unused, and so ought to have no impact.
- Templates extending `domestic_header.html` and `international_header.html` can now only overwrite the header_logo. All other overwrites are no longer allowed. I believe no templates do this, so there ought to be no impact.
- Templates overwriting the `header_logo` on `domestic_header.html` and `international_header.html` should now use a `header_logo.html` block to do so, instead of just an image. I believe no templates do this, so there ought to be no impact.
- `dit.classes.Dropdown.js` has been removed. This should no longer be required anywhere, so can be safely removed.
