DOM: Svg attributes and tag names are being lowercased #18090
Description
Description
All attributes are being lowercased, but for svg elements they should have correct casing (e.g. viewbox should be viewBox).

Lexbor does have this attribute mapping in the code, so maybe php is just skipping it somehow: https://github.com/lexbor/lexbor/blob/9283215c15c3c7a5106a1a1e3ff16ff89900a1a5/source/lexbor/html/tree_res.h#L31
