default text/font rendering not working as expected.

[5achinJani]

below is my svg:

<svg
	xmlns="http://www.w3.org/2000/svg"
	xmlns:xlink="http://www.w3.org/1999/xlink" style="isolation:isolate;" viewBox="0 0 1 1" version="1.1">
	<rect width="1" height="1" fill="#6D4C41"/>
	<text x="50%" y="50%" style="font-size: 0.5px" fill="#FFF" text-anchor="middle" dy=".178">SS</text>
</svg>

node-svg2img function is executed with the above svg and no other options.
Image png output:

I suspect this has something to do text positioning maybe?

Browser output: fiddle link
