Thumbnails generated by Inkscape show tiny under macOS

Summary:

Since a few macOS versions, Finder (the file explorer) shows SVG thumbnails super tiny:

Steps to reproduce:

Just create any SVG with Inkscape and turn Finder into icon view. You can even try the "Quick look" feature, it will show the drawing so small aligned top-left

What happened?

I don't know, but initially thought it was something related with Finder itself but... it doesn't happen with Illustrator and other vector programs so I tried to compare them "reading the code". I was tinkering with the <svg> tag attributes and found out that the problem comes from these two lines:

height="64"
width="64"

Indeed the problem is not the number (in this example 64 because the SVG files where set to 64x64 pixels) but the height and width attributes.

If you just delete them from the Inkscape generated SVG then Finder will show them perfectly.

What should have happened?

Version info
