+// Temporary fix for a bug with Chrome 129 when handling mask-image
+// OUI provides the mask-image used in these which Chrome 129 fails to render correctly.
+// It is not known if or when Chrome will fix this. Since almost all of these classes
+// are applied to elements with scrollbars where their content contained, containing the
+// paint is a safe solution.
+// This can be achieved with various tricks like transform: translate?(0) or
+// transform-style: preserve-3d but they add to the browsers workload; contain doesn't.
+// ToDo: Remove these when most used versions of Chrome no longer suffer from the bug.
+// From OUI: any ruleset containing mask-image
