See the original report in #10772 (comment).
The problem is that SVG is case sensitive, and so naïvely setting tabIndex
and relying on insensitivity won't work with it.
The good news is it seems like tabindex
is the only valid SVG attribute with this problem. We just missed it because it applies both to HTML and SVG.
I think the fix is to add it back to the whitelist.
