            Bug ID: 224364
           Summary: Change WebXRSpace::efectiveOrigina() matrix
                    multiplication order
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebXR
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ifernandez at igalia.com

The current multiplication order is not working correctly when combining local-floor space and getOfffsetReferenceSpace(). The reference space is out of sync with input ray pose after some teleportations (tested using https://github.com/immersive-web/webxr-samples/blob/main/teleportation.html).

There is a WPT test to reproduce this but we can't enable it yet until we fetch it from upstream (https://github.com/web-platform-tests/wpt/pull/28024), currently blocked by WebGL 2 support in WPE.
