sprite sheets don't work on macOS browsers

[gzzo]

I created a minimal repository to reproduce: https://github.com/gzzo/spritesheet_demo

using cargo run you can see the sprite sheet loaded locally

using wasm-pack build --target web --release (and copying the assets to pkg/) you can't see the sprite sheet

Probably related to #20.

It depends on your browser, its version, your os and your gpu...

Confirming that this works on:

• Windows Chrome and Firefox

But does not work on:

• macOS Chrome, Firefox, and Safari

works for me on Firefox macOS (to test: https://mrk.sed.pl/bevy-showcase/#sprite_sheet)
