UnrestrictedSharedArrayBuffer - Onshape integration

[zrnnn]

Kiri:Moto currently fails to load within the Onshape iFrame on Chromium-based browsers. It hangs and throws the following error:
"Security context of this window prevents animations. Try a Chromium based browser instead."

Root Cause:
I checked the DevTools, and it looks like the Google Origin Trial token for UnrestrictedSharedArrayBuffer on grid.space has expired a few days ago.

Expiration Date: May 19, 2026 at 02:00:00 CEST

Token Status: Expired

Environment:

Browser: Chromium-based (v148.x) / Linux

Platform: Onshape via iframe (grid.space)

the reverse origin trial has ended and no new tokens are available. I am at the mercy of Onshape who needs to update their iframe headers. I have raised this with them repeatedly over the last two years without success.
