    <thetext>Tokenisation and parsing for whitespaces described in CSS Syntax Module Level 3 matches the current WebKit behavior in custom properties.
Some WPTs still have wrong expectations.

Both leading and trailing whitespaces should be stripped:

https://drafts.csswg.org/css-syntax/#consume-declaration

    2. While the next input token is a &lt;whitespace-token&gt;, consume the next input token.
    ...
    7. While the last token in decl’s value is a &lt;whitespace-token&gt;, remove that token.&quot;

Middle whitespaces collapse to a single &lt;whitespace-token&gt;:

https://drafts.csswg.org/css-syntax/#consume-token

    whitespace
    Consume as much whitespace as possible. Return a &lt;whitespace-token&gt;.</thetext>
