Bug 246191 – Remove SVGTRefElement Support

• Component: SVG
• Status: NEW

[Ahmad Saleem]

Hi Team,

I am creating this bug to align Webkit with other browsers to remove support for "SVGTRefElement".

Chrome / Blink Patch - https://src.chromium.org/viewvc/blink?revision=157630&view=revision

CANIUSE - https://caniuse.com/mdn-api_svgtrefelement (Only supported by Safari)

Didn't manage to find separate bug so created this one.

Thanks!

Nikolas said on Slack:
> <tref> is rarely used - I never used it for anyting. It can go IMHO.
