[yew-devel] [PATCH proxmox-yew-widget-toolkit-assets] infinite progress bar: use purely transforms for the animation

[Dominik Csapak]

this has the advantage that it works even when the wasm/js code blocks
the browser, the animation can still continue. When using `left`, that
seemingly triggers a reflow/layout and can't be done until wasm/js is
done.

Visually there should be no difference.
