+Subject: [PATCH] Fix QQuickMouseArea getting stuck in pressed state when
+ hiding in press
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+In 78c1fcbc49f56463064eef738a475d9018357b24 we stopped giving the
+exclusive grab to hidden or disabled items with is good. But the change
+did not take into consideration how mouse area handles its internal
+state.
+
+As a simple example: A mouse area that would set itself hiddin in the
+press handler, would continue to have d->pressed == true, which means it
+would not react to any future press events.
+
+The fix is to let mouse area check in its change handler whether it has
+become invisible.
+The test also checks that enabled behaves the same way. There is no
+action needed, since mouse area does completely custom handling of
+enabled (maybe something to fix in Qt 6), disabling a mouse area doesn't
+disable its children for example, it doesn't invoke
+QQuickItem::setEnabled at all. Due to this circumventing the common
+behavior, by chance disabling a mouse area in the on pressed handler
+works.
+
+Fixes: QTBUG-74987
