421000 - sidebarheader tag has no XBL binding

Status: RESOLVED WONTFIX

(Firefox :: General, defect)

Description

[Myk Melez [:myk] [@mykmelez]]

browser.xul uses a <sidebarheader> tag, but there's no XBL binding for that tag, so it's not clear why we don't simply use a <box> or the like.  

Note: the suite binds its <sidebarheader> tag to an XBL binding <http://mxr.mozilla.org/mozilla/source/suite/themes/modern/communicator/sidebar/sidebar.css#58>, although only one of its two themes (modern) actually implements that binding <http://lxr.mozilla.org/mozilla/source/suite/themes/modern/communicator/sidebar/sidebarBindings.xml#56>.

I guess an alternative solution would be to implement the binding, but I doubt the sidebar header is complex enough to justify an XBL binding for the one instance of it in the code.

I don't think there's a good reason for it to have it's own tag name. It would be  nice to remove the bogus style rules in toolkit for it, too...

xbl is dead, long live xbl.

(also these elements are gone)
