MuJoCo Live doesn't work on iPhones

### Intro

I am a MuJoCo maintainer.

### My setup

Safari on iPhone

### What's happening? What did you expect?

MuJoCo Live (our WIP interactive web viewer) pages, e.g.

https://live.mujoco.org/?model=github:google-deepmind/mujoco/main/model/humanoid/humanoid.xml

work great on all platforms we tested, including macOS, but crash on iPhone for some reason. What are we doing wrong?

### Confirmations

- [x] I searched the [latest documentation](https://mujoco.readthedocs.io/en/latest/overview.html) thoroughly before posting.
- [x] I searched previous [Issues](https://github.com/google-deepmind/mujoco/issues) and [Discussions](https://github.com/google-deepmind/mujoco/discussions), I am certain this has not been raised before.

Start by opening the provided MuJoCo Live humanoid URL in Safari on an iPhone and reproduce the crash, then compare it with the platforms where it works. Gather the available Safari or device failure details and verify that the page loads successfully on iPhone without crashing.
