Mac here. There's nothing all that interesting going on with the JS on that page, so I would suspect a bug with Firefox and/or your desktop environment.
> The site’s graph incorrectly uses 32 texture bindings, exceeding its WebGPU device’s limit of 16.
> Firefox 153 mishandles that failed rendering operation and leaves the compositor waiting
So a firefox + website bug
With an updated firefox, the website works except the mindmap on the top right
> Uncaptured WebGPU error: Too many bindings of type SampledTextures in Stage ShaderStages(FRAGMENT), limit is 16, count was 32. Check the limit `max_sampled_textures_per_shader_stage` passed to `Adapter::request_device`
