+Subject: [PATCH] Never handle scrollbars styled with box or border changes as
+ transient
+
+If scrollbars are styled with a style sheet that includes a box or
+removes off the native border, then we never treat them as transient or
+overlapping. Otherwise, the layout logic in QAbstractScrollArea will
+show them on top of the viewport, overlapping the content.
+
+The cherry-pick doesn't include the base line test from the upstream
+change, as the testing framework is not available in 6.2.
+
+Fixes: QTBUG-98289
