It won’t help with dark mode, but the canvas-place-element proposal (https://github.com/WICG/canvas-place-element) should allow those interactions on canvas-rendered text backed by a text element placed under the canvas.

In Chrome, it selects sometimes but sometimes it seems to unselect itself, probably due to the animation happening somewhere else on the page.

My Firefox on Linux zooms fine with both renderers. Text selection doesn't work though. Also the cursor doesn't adapt when hovering text, a button etc.

Zooming is indeed an issue but selection works fine for me on safari ios.

On Windows/Firefox, text selection doesn't work. Also not working is Home/End and wheel click scrolling. Cool project otherwise.
