  -----------
  Make `iframe` containing SVG behave as every other `iframe`

https://bugs.webkit.org/show_bug.cgi?id=266702

Reviewed by Tim Nguyen.

This patch aligns WebKit with Gecko / Firefox and Blink / Chromium.

Inspired by: https://src.chromium.org/viewvc/blink?view=revision&revision=172467

When an SVG is contained inside an `iframe`, its dimensions should not
be part of size calculations of the `iframe`. Neither should the SVG's
own width and height be ignored when sizing the `svg` inside the
`iframe`.

(RenderWidget::embeddedContentBox): Extended check for 'embeddedObject'
* Source/WebCore/rendering/svg/legacy/LegacyRenderSVGRoot.cpp:
(LegacyRenderSVGRoot::isEmbeddedThroughFrameContainingSVGDocument): Aligned with LBSE
