Bug 265967 – Fix failing '%' valid and invalid 'shape-image-threshold' parsing tests

• Status: NEW
• Component: CSS

Hi Team,

While going through bug 191939, I noticed that we fail 'shape-image-threshold' test for % values and while looking into Safari failures on WPT, I came across us failing following:

WPT Test Cases: https://wpt.fyi/results/css/css-shapes/parsing?label=master&label=experimental&aligned=&q=shape-image-threshold+safari%3Afail

I just wanted to raise this as separate so we can track it better.

Thanks!

Changing `CSSProperties.json` from:

"style-converter": "Number<float>",
                "parser-grammar": "<number>"

to

"style-converter": "Opacity",
                "parser-grammar": "<alpha-value>"

It fixes - shape-image-threshold-computed.html but it also lead to failure in `css/css-typed-om/the-stylepropertymap/properties/shape-image-threshold.html`.

We still need to fix `invalid` test post above fix.
