My application crashes since Qt 5.15.7 (5.15.6 worked) only on Android:

The debug output shows:
QMetaObject::invokeMethod: No such method QQuickPopupItem::inputMethodQuery(Qt::InputMethodQuery,QVariant) F libc : Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x4 in tid 25297 (qtMainLoopThrea), pid 23512 (com.myapp)
The problem happens when a Qml popup menu is opened multiple times. The debug output is similar to this bug: QTBUG-82810. Attached is an example.
