The example in the MDN documentation renders without scroll bars in Chrome 86.0.4240.198 .
<svg viewBox="0 0 200 30" xmlns="http://www.w3.org/2000/svg" overflow="auto">
<text y="20">This text is wider than the SVG, so there should be a scrollbar shown.</text>
</svg>
I have changed the example to overflow="scroll"
and it still does not work correctly (i.e. it does not show scroll bars). Is there a work around?
