1175919 - Integer attribute handling doesn't follow the spec

Status: NEW

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

Description

[Olli Pettay [:smaug][[e-mail]]]

Gecko's implementation seems to just ignore trailing non-digits, but
https://html.spec.whatwg.org/multipage/infrastructure.html#rules-for-parsing-integers says
"If the character indicated by position is not an ASCII digit, then return an error."

Interesting.  On your testcase, Blink/WebKit seems to treat "200$" as "200", but treat "200*" as error?

Also see the discussion in bug 1071508.

Found the wider context for this discussion at http://logs.glob.uno/?c=freenode%23whatwg&s=18%20Jun%202015&e=18%20Jun%202015#c951803 and following.

We should check what other UAs (IE, I guess) do.  It's possible that the spec is simply not web-compatible here.
