> The problem seems to be that the margin never shrinks below 1 causing the width including the margin to extend past the container for zoom levels below 100%.

...and that logic is in CSSPrimitiveValue::computeLengthDouble:

    // Any original result that was >= 1 should not be allowed to fall below 1.  This keeps border lines from
    // vanishing.
    double zoomedResult = result * multiplier;
    if (zoomedResult < 1.0 && result >= 1.0)
        return 1.0;

This should probably only kick in for borders (which are represented as integers).
