1429415 - Don’t report parse error if </caption> end tag is missing

Status: RESOLVED DUPLICATE of bug 1650320

(Core :: DOM: HTML Parser, defect, P3)

Description

[Michael[tm] Smith [:sideshowbarker]]

If you open view-source:data:text/html;charset=utf-8,%3C%21DOCTYPE%20html%3E%3Ctitle%3Etest%3C%2Ftitle%3E%3Ctable%3E%3Ccaption%3E%3Ctr%3E%3Ctd%3E%3C%2Ftable%3E in Firefox you’ll see the <tr> start tag is displayed in red, and if you mouse over it, you’ll see a tooltip with the error text «Stray start tag “tr”.»

But due to https://github.com/whatwg/html/commit/759ee62, the HTML spec now allows the </caption> end tag to be omitted, and the HTML parsing algorithm no longer defines the case of a </caption> end tag as a parse error.

Therefore, Firefox should not render that <tr> start tag in red, and no error text should be shown.
