Yuichi Nukiyama (@YuichiNukiyama) Thanks for your great work.

I found I cannot select an SVGTitleElement (https://developer.mozilla.org/en-US/docs/Web/API/SVGTitleElement) by querying "title" with SVGSVGElement's querySelector(). I think the problem is related to this PR.

I think it would be nice if querySelector("title") returns a value of type HTMLTitleElement | SVGTitleElement.

How do you think?

A good point. However, cast is necessary, so it is hard to use.
