test($compile): skip failing foreignObject test on MS Edge

For unknown reasons, an `<svg>` element inside a `<foreignObject>` element on MS Edge seems to have
no size, causing the included `<circle>` element to have no size as well and thus fails an
assertion (relying on the element having a non-zero size).

This seems to be an MS Edge issue; i.e. it is also reproducible without Angular.
(Tested with MS Edge version 25.10586.0.0 on Windows 10.)
