Minimal Duplication of this bug

Interactive elements containing the `<svg>` element which is named by `<title>` element doesn't have accessible name. Other major browsers provide accessible name, and this is tested by WPT.

- https://wpt.fyi/results/svg-aam/name/comp_host_language_label.html?label=experimental&label=master&aligned
- https://github.com/web-platform-tests/wpt/pull/56902

And if we link `<title>` to `<svg>` elements using `aria-lablledby`, accessible name is provided as expected.

Maybe this is because `accessibleNameDerivesFromContent` lacks `AccessibilityRole::GraphicsDocument` case (If this is true I wanted to fix it, but WebKit build failed on my WSL).

- graphics-document role is named from author: https://w3c.github.io/graphics-aria/#graphics-document

This is used to decide how to calculate the accessible name using its child elements.
