Steps to reproduce:
Visit https://smplr.me/BLZQAAx. On first load, the 3D assets take a few seconds to load which is normal. The bouncing sphere represent the loading state. Then refresh, the assets are cached and should load much faster.
I’ve tried to profile the browser (Firefox Dev Edition) during the load but I’m not seeing anything that explains why everything is loading for so long, see my recorded profile at Firefox Profiler 1 if that helps.
The cached assets (I’ve confirmed they are cached from the network tab in the devtools, after a reload) are extremely slow to load. The bouncing sphere are displayed for a few seconds (sometimes over 10s) even after they are displayed as loaded (cached in this instance) in the network tab.
To make things more complicated, this happens only with Firefox Developer Edition and Safari, but not with Firefox, Chrome, Chrome Dev, Edge, or Edge Dev. The experience is consistent with all browsers.
I'm expecting Firefox Dev Edition (90.0b12) to load the cached assets as fast as Firefox (89.0.2) does.
