Extract the state that controls mass tag form in the posts list header
to a separate class.
It's not exactly a 100% reusable control (the .tpl is shared), but it
should greatly simplify reading the JS.
Print all links through new uri.js component
Refactor the router to use more predictable parsing
Fix linking to entities with weird names (that contain slashes, + etc.)
Visiting mass-tag URL directly ignored masstag privileges and showed
tag/untag controls (although didn't show the controls in the header).
After this change, bypassing mass tag privileges got a little bit
harder. (It's still possible for the user to talk directly to the API
after all.)
In e464e69 I removed href='#' but I noticed that it broke some things.
Readding href serves two purposes:
- it makes links reachable with Tab key
- it makes links clickable with Enter key
The alternative to this approach was to introduce [tabindex] and [role]
attributes. But not only using tabindex=0 with <a/> is questionable,
it'd require adding a keyboard handler that'd intercept space and return
key presses and simulated link clicks. Since it's best to leave this
kind of thing to the native UI, I went with readding hrefs instead. I
believe that hash hrefs, even though being a common practice, are silly,
so I decided to settle down with empty hrefs.
As a bonus, I added a snippet that prevents middle mouse clicks from
opening such links/buttons in new tabs, which was the motivation for
e464e69.
