Bug ID: 219482
Summary: [WPE]
imported/w3c/web-platform-tests/webxr/xrSession_cancel
AnimationFrame_invalidhandle.https.html is flaky
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: New Bugs
Assignee: webkit-unassigned at lists.webkit.org
Reporter: dpino at igalia.com
The test sometimes fails with the following output:

PASS XRSession cancelAnimationFrame does not have unexpected behavior when given invalid handles on immersive testSession
PASS XRSession cancelAnimationFrame does not have unexpected behavior when given invalid handles on non-immersive testSession
It's possible to reproduce the failure with the following command:
$ Tools/Scripts/run-webkit-tests --wpe --release --iterations=3 imported/w3c/web-platform-tests/webxr/xrSession_cancelAnimationFrame_invalidhandle.https.html
I think the problem is in https://webkit-search.igalia.com/webkit/source/LayoutTests/imported/w3c/web-platform-tests/webxr/resources/webxr_util.js#22, that block of code is meant to be executed only once but sometimes is executed more than once.
