- Updated tab handling to be smarter on initial tab selection, to first
target non-hidden tab panels where they may be handled server-side.
- Extracted contained search box handling styles to _forms.scss, after
merging with image-manager-specific styles since this is only usage of
contained variant.
- Aligned focus handling on image manager UI elements.
Makes interface relatively usable now on mobile sizes.
Required updating of tab handling to support tabs being active at only
mobile screen sizes, include change on resize, upon support for
potentially nested tab usage.
Tab component will now search within sensible depths for finding its own
tabs and panels to control.
Added use of more accessible tags to create tabbed-interfaces then
updated css and JS to require use of those attributes rather than custom
techniques.
Updated relevant parts of app.
Some custom parts using their own tabs though, something to improve in
future.
- Created new dropzone component.
- Added standard component event system using custom DOM events.
- Added tabs component.
- Added ajax-delete-row component.
