1121475 - Why is <command> treated as a void HTML element by IsVoidTag/IsHTMLVoid and in the sanitizer whitelist?

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Boris Zbarsky [:bzbarsky]]

I see no such element in the HTML spec...

Hmm, wasn't <command> part of the <menu> mess.
The spec used to have something odd, we implemented something simpler and IMO saner, and yet the
spec ended up looking still something different. But <command> got removed somewhere in the process.

But <command> is now gone, AFAIK.

We have <menuitem> which is similar and void too. Hixie didn't like it originally, but after several years he updated the spec to be closer to implementation in Firefox. IIRC, he removed <command> and introduced <menuitem> in the spec.

[Henri Sivonen (:hsivonen)]

The answer to the question posed in the summary is basically "historical reasons". We should update things to the current spec.

Attachment: Drop special handling of HTML <command> in the void tag list and the sanitizer whitelist, since there is no HTML <command> tag
