Bug 165516 – Div inside SVG foreignObject loses its position and not visible

• Component: SVG
• Status: RESOLVED DUPLICATE

[sinish]

I tried to run this HTML5 SVG code in MAC chrome (54.0.2840.98 (64-bit)); but the DIV inside the become invisible (or seems to be losing its position/jumping out from the SVG) when content in the DIV Overflows or scrollbar comes. However it works perfectly in MAC Firefox and all browsers in Windows (except Mobile views).


Is it any issue regarding

viewport metadata?
div inside ForeignObject?
MAC chrome bug?
CSS? How can we solve this?. Your help is much appreciated.

Reproduces in Safari 10 - the rendering is different from Firefox. It's visible though.

Same test as an attachment.

I think this is about how <foreignObject> needs to act as a rendering root but currently does not.

Broken in Chrome (55.0.2883.75) as well.

[Said Abou-Hallawa]

This bug happens because RenderSVGForeignObject is not a rendering root.
RenderSVGForeignObject::requiresLayer() currently returns false.
