why does rotating an svg clip path cause stuttering / not work? - css

Question

I'm trying to make an svg clip path spin in a circle using css animations, I use transform: rotate to make it rotate but this seems to produce jerky motion (or no motion):
in firefox it moves but jerks.
in chromium browsers the position only seems to update when the page is interacted with.
here's my code:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 76.0146 47.6272">
<defs>
<style>
.magnifyingGlass {
animation: spin 10s infinite linear;
transform-origin: 50% 50%;
will-change: transform;
}
#keyframes spin {
0% {transform: rotate(0deg);}
100% {transform: rotate(360deg);}
}
</style>
<linearGradient id="primary_gradient" data-name="primary gradient" x1="24.8437" y1="23.8283" x2="51.1709" y2="23.8283" gradientUnits="userSpaceOnUse">
<stop offset="0.2367" stop-color="#f78739"/>
<stop offset="0.9428" stop-color="#f73c39"/>
</linearGradient>
<clipPath class="magnifyingGlass" id="clip-path">
<circle cx="48.1997" cy="13.636" r="9.5"/>
</clipPath>
