[Bug] WASM CompileError: wasm validation error at offset 236: bad type on Android Firefox when loading 3DGS scene

[whwhwwhwwh]

Loading Spark 3DGS on Firefox Android triggers CompileError: wasm validation error: at offset 236: bad type.

Works normally on Android Chrome and all desktop browsers(Chrome/Firefox/Safari), only Firefox for Android fails WASM module compilation and cannot initialize 3DGS rendering.

Environment:

• Spark Version: v.2.1.0
• Firefox Android Version:151.0.3
• Android OS: Android 12

I'm unable to reproduce the issue on Android 12 with Firefox or Fennec, both running version 151. It might be due to a WASM feature Spark depends on that for some reason isn't supported/enabled on your specific device/OS/browser setup.

Just to be sure, does the same issue occur when opening any of the examples on sparkjs.dev?

Could you also post the list of WASM features detected here: https://wasm-feature-detect.surma.technology/.

Thanks for your reply.
I've tested on two Android 12-based devices:
Huawei Mate30 | HarmonyOS 4.2.0 (Android 12)
Redmi K60E | MIUI 13.0.5 (Android 12)
All demo examples from sparkjs.dev end up with black screen on both phones, the problem can be fully reproduced.
I will attach the WASM feature detection result screenshot as requested below.
