Bug 255844

Hi Team,

While going through Blink's commit, I came across following UA Stylesheet update commit:

Commit - https://chromium.googlesource.com/chromium/src/+/c5ecd6d100aeefb1b77c310beb11e458fc2d139c

Failing WPT Test Case - http://wpt.live/css/css-tables/html-to-css-mapping-1.html

Web-Spec: https://html.spec.whatwg.org/#tables-2

Our UA Stylesheet does not have following:

td, th { padding: 1px; }

^ Adding this manually in the local branch fixed the failing sub-test in WPT testcase but I don't know whether it would've any unintended effect.

Blink added this with different rule in their stylesheet because they had some styling enforced via HTMLTableCellElement::AdditionalPresentationAttributeStyle() function.

I didn't find any special styling within WebKit in HTMLTableCellElement though.

Appreciate if someone can confirm, if my understanding is right and I am happy to do PR.

Thanks!
