<foreignObject> is treated as a containing block for all descendants in Chromium. It's also a stacking
context, as of Chromium 67.

The SVG2 spec says, at least indirectly, that <foreignObject> is both a stacking context and containing block. This sentence in particular:

"Since the ‘foreignObject’ element creates a "fixed position containing block" in CSS terms..."

Therefore it's web compatible, as far as it concerns Chromium, to define SVG container elements
as establishing a containing block for all descendants.
