Created attachment 474774 [details] HTML example Applying the browser zoom to a page has outsized effect on the content of foreign objects in SVG. An image as simple as the following Text: <svg width="100" height="20"><foreignObject width="100" height="20">Text</foreignObject></svg> shows how the two words 'Text' change size very differently with the browser zoom. Screenshots attached.
