Hi Team,

This is to fix test case:

WPT Live Link: http://wpt.live/html/semantics/embedded-content/the-embed-element/embed-hidden-attribute.html

Blink Commit: https://chromium-review.googlesource.com/c/chromium/src/+/3565492

________

Adding following in UA Stylesheet:

embed[hidden] { 
    display: inline; 
    height: 0; 
    width: 0;
} 

or fix by merging Blink Commit:

_____

UA Stylesheet fixes this above test case in WebKit but haven't run any test suite locally to confirm, if it regresses anything.

Thanks!
