++Correction in latest chrome version# 73.0.3628.0

Given that making the <svg> have 'overflow: hidden' (i.e removing the inline style overriding the UA rule) makes it display again, woxxom's bisect result seems more likely to be correct. I guess this is caused by overflow somewhere yielding an empty rectangle when it shouldn't.

The following revision refers to this bug:

Clamp contents visual overflow for LayoutSVGRoot

If the contents overflow rect for the SVG root is too large, it could
end up shifting the overflow rect such that it is culled and thus never
painted.

To avoid this, clip the content overflow rect with
LayoutRect::InfiniteIntRect(). This gives reasonable enough leeway, and
also matches the rect that is commonly used to represent infinity for
culling and clipping etc.
