Emacs stopped showing SVG files completely (i.e. it is shown cropped), with 8f42b94fe43 the offending commit. This commit intends to resolve bug#40845.

Please find the SVG file (1.svg) I use and the render image (1.png) in attachment. Notice the cropped part at the bottom and on the right side. The SVG file can be correctly viewed by Emacs 27, and other photo viewers like eog or gThumb. The file attached embeds an SVG element inside another, which seems to be discouraged by https://debbugs.gnu.org/cgi/bugreport.cgi?bug=40845#68. However, according to Mozilla MDN (https://developer.mozilla.org/en-US/docs/Web/SVG/Element/svg),

> The svg element is a container that defines a new coordinate system and viewport. It is used as the outermost element of SVG documents, but it can also be used to embed an SVG fragment inside an SVG or HTML document.

> Note: The xmlns attribute is only required on the outermost svg element of SVG documents. It is unnecessary for inner svg elements or inside HTML documents.

So the file IS a valid SVG file.
