When importing SVG, Figma ignores the stroke-width set in svg and adds its own

[Streamline]

Hello, we are having an issue when importing SVGs into Figma.

Apparently, when viewBox’s width/height doesn’t match width/height attributes of SVG, Figma changes viewBox’s width/height to match width/height attributes, but also it scales the set stroke-width in the same way. This results in confusion, as externally explicitly set stroke-width gets changed when imported into Figma.

This simple SVG

<svg xmlns="http://www.w3.org/2000/svg" height="200" width="200" viewBox="0 0 100 100">
	<circle cx="50" cy="50" r="40" stroke="black" stroke-width="3" fill="red" />
</svg>

…gets converted into this when I import it into Figma (retrieved by copying its SVG):

<svg width="200" height="200" viewBox="0 0 200 200" fill="none" xmlns="http://www.w3.org/2000/svg">
	<path d="M100 180C144.183 180 180 144.183 180 100C180 55.8172 144.183 20 100 20C55.8172 20 20 55.8172 20 100C20 144.183 55.8172 180 100 180Z" fill="#FF0000" stroke="black" stroke-width="6"/>
</svg>

As you can notice, stroke-width got multiplied by 2, as viewBox’s width/height also got multiplied by 2.

I would love to avoid this when importing SVGs into Figma, how is it possible? Or perhaps how can I prepare SVG with code so that, when imported into Figma, the stroke-width doesn’t change and yet the certain size Is used? Thank you!
