SVG reference element such as <use>.
See related GHSA-9wjq-cp2p-hrgf in Loofah, whose SVG local-reference
logic rails-html-sanitizer mirrors.

## Impact

`Rails::HTML::PermitScrubber` restricts SVG reference elements in the
`SVG_ALLOW_LOCAL_HREF` collection to local, same-document references,
but that restriction covered only the `xlink:href` attribute. Browsers
also accept a plain `href` attribute per the SVG 2 spec, and it was
not restricted, so those elements could reference arbitrary external
documents. SVG `<use>` can load and render external SVG content by
reference, and if the referenced document is same-origin and contains
scripts, it could execute in the context of the sanitized document.
`<feImage>` can load external images, which can be used for tracking.

Applications are impacted only when the allowed tags are overridden
to include one of these SVG reference elements, for example `<use>`
or `<feImage>`. The default allowed tags do not include these SVG
elements, so applications using the default configuration are not affected.
