Summary Twelve css WPTs are failing with async overflow scrolling enabled on macOS

Eight WPTs from the `css/` directory are failing in ToT with the `AsyncOverflowScrollingEnabled` web preference set to true. A couple of the failures are not concerning, but at any rate, here is a summary. The failed tests: imported/w3c/web-platform-tests/css/compositing/mix-blend-mode/mix-blend-mode-parent-element-overflow-scroll.html imported/w3c/web-platform-tests/css/css-grid/grid-model/grid-container-scrollbar-vertical-lr-001.html imported/w3c/web-platform-tests/css/css-grid/grid-model/grid-container-scrollbar-vertical-rl-001.html imported/w3c/web-platform-tests/css/css-masking/clip/clip-rect-scroll.html imported/w3c/web-platform-tests/css/css-overflow/overflow-auto-scrollbar-gutter-intrinsic-003.html imported/w3c/web-platform-tests/css/css-position/position-fixed-scroll-nested-fixed.html imported/w3c/web-platform-tests/css/css-scrollbars/textarea-scrollbar-width-none.html imported/w3c/web-platform-tests/css/css-ui/outline-negative-offset-composited-scroll.html Of these eight tests, `imported/w3c/web-platform-tests/css/css-overflow/overflow-auto-scrollbar-gutter-intrinsic-003.html` and `imported/w3c/web-platform-tests/css/css-scrollbars/textarea-scrollbar-width-none.html` only have a 0.01% image diff, and shouldn't really be failing. While the other tests have regressed, they now show the same failure mode as what WebDriver produces (i.e. WKTR test results and wpt.fyi test results match).
