Tests: Fix the "outside view position" test in Headless Chrome

mgol · web-flow · commit 23d72cb1db8f · 2025-11-24T18:25:00.000+01:00
In Headless Chrome, when run locally on macOS together with a few other modules, the scroll handler for the appended element in the "outside view position" dimensions test doesn't fire, timing out the test & failing it as a result. While the scroll handler may not fire, the new position data is available immediately, so just do the checks directly, without relying on scroll handlers. Closes gh-5728 Ref gh-5729
