iAPI Router: Styles inside `noscript` tags are wrongly applied on client-side navigation

[DAreRodz]

Description

The <style> or <link rel=stylesheet> elements inside <noscript> sections are handled as if they were placed outside and applied to the page after client-side navigation, which is not correct. These elements can be simply ignored, as the Interactivity API doesn't work without JavaScript.

Step-by-step reproduction instructions

1. Add a block of HTML in a template with a Query Loop block, with a <noscript> element and a <style> tag that changes the body background within. E.g.:

   <noscript><style>body{ background: red !important; }</style></noscript>

2. Ensure "force page reload" is disabled in the Query Loop block.
3. Visit a page with the modified template.
4. Navigate to the next page.
5. The body background color wrongly changes.
