Re: [csswg-drafts] [css-anchor-positioning-1] [scroll-animations-1] [css-view-transitions-1] Scoping names on elements based on tree scope (#10304)

@flackr pointed out that `@property` declarations behave as per spec, i.e., declarations in the outer scope are visible in inner scope. Here is an example: https://jsbin.com/xoqebek/edit?html,output (credits to @flackr).

```
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">

<body>
<div id="host">
  <template shadowrootmode="open">
    <div class=outer>I'm in the shadow DOM using outer names</div>
    <div class=inner>I'm in the shadow DOM using inner names</div>
    <style>
      @property --inner-property {
        syntax: "<color>";
        inherits: false;
        initial-value: green;
      }
      @keyframes inner-anim {
        from { opacity: 1;}
        to { opacity: 0;}
      }
      .outer {
        animation: outer-anim 1s infinite;
        color: var(--outer-property);
      }
      .inner {
        animation: inner-anim 1s infinite;
        color: var(--inner-property);
      }
    </style>
  </template>
</div>
  <style>
    @keyframes outer-anim {
      from { opacity: 1;}
      to { opacity: 0;}
    }
    @property --outer-property {
      syntax: "<color>";
      inherits: false;
      initial-value: green;
    }
    #outer {
      animation: outer-anim 1s infinite;
      color: var(--outer-property);
    }
    #outer-inner {
      animation: inner-anim 1s infinite;
      --inner-property: jfaowiej; /* not a valid color so will be discarded if property registration is used. */
      color: var(--inner-property);
    }
  </style>
  <div id="outer">I'm in outer DOM using outer names</div>
  <div id="outer-inner">I'm in outer DOM using inner names</div>
</body>
