I have a 20MB SVG file (essentially some 150000 small circle elements). While rendering it, the Firefox UI exhibits a lot of jank. Perhaps the SVG content can be rendered in a different thread?
Version: 15 Branch → 18 Branch
Can you attach the SVG file or host it somewhere?

Doesn't seem to be any UI jank any more for me. Each tab is in a different thread these days.
