It's very easy to lock up your browser or machine with WebGPU, it happens on Windows too. You'll do this by accident constantly in a big WebGPU project, until the Chrome GPU trace/renderdoc/nsight shows some crazy deadlock bottleneck you have no hope of understanding at the browser level.

GPU driver engineering has received a tiny fraction of the resources of CPU engineering, while being significantly more complex. And GPU users will not pay for performance hits that better the architecture, they will just buy the other guy's GPU/use their driver. So it's a race to the top with performance and race to the bottom with architecture and stability.
