A DOM-to-image snapshot draws the page's noscript content

Fact

Libraries that turn the DOM into an image (modern-screenshot, html-to-image, dom-to-image) clone the page into an SVG <foreignObject> and load that as an image. An SVG image runs with scripting disabled, so every <noscript> element in the clone renders, and its fallback text appears in the picture.

Why it matters

A "this page needs JavaScript" line shows up over the top of a screenshot of a page that is plainly running JavaScript. Nothing on screen explains it, and the libraries do not strip <noscript> by default.

How to apply

Leave <noscript> out with the library's node filter:

domToCanvas(document.body, { filter: (node) => node.nodeName !== 'NOSCRIPT' });
