1959826 - SVG2: Reference entire files with <use>

Status: UNCONFIRMED

(Core :: SVG, enhancement)

Description

[James Prevett]

Attachment: test.html

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:137.0) Gecko/20100101 Firefox/137.0

Steps to reproduce:

I attempted to use the <use> element with an href pointing to an entire SVG document.

According to the SVG 2 spec. (https://www.w3.org/TR/SVG2/struct.html#UseElementHrefAttribute):

New in SVG 2. An ‘href’ without a fragment allows an entire SVG document to be referenced without having to ensure that it has an ID on its root element.

To reproduce the bug:

1. Create a new HTML document
2. In the HTML document, create a <svg> with a <use> with a href without a fragment
3. Create an external SVG document
4. Notice the external SVG document referenced is missing in the HTML document

I've uploaded test.html, which includes a simple HTML document for testing. You can then add a test.svg file in the same directory with these contents: <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100"><circle cx="50" cy="50" r="30" /></svg>.

Actual results:

When referencing an entire SVG document with <use>, the referenced document is not loaded.

Expected results:

Referencing an entire SVG document with <use> should correctly load the entire external document.
