Minimally reproducible example:

<svg width="100" height="30" version="1.1" xmlns="http://www.w3.org/2000/svg">
    <rect width="100" height="100" fill="white"></rect>
    <g transform="scale(.1 .1)">
        <line x1="0" x2="100" y1="150" y2="150" stroke="#000" stroke-width="5"/>
    </g>
</svg>

What it should look like:

What it actually looks like:

Looks to me like the stroke-width property is not affected by the scale, even though it should.

Once this PR gets merged, this issue should be fixed.
