[Reg 5.12.4 -> 5.14.0] Android: 'module "QtQuick" plugin "qtquick2plugin" not found'

I have installed Qt 5.14.0-beta1 android_armv7 via online installer. Building/deploying/running Qt Widget applications works fine, Qt Declarative applications on the other hand exit immediately:

W/libuntitled38_armeabi-v7a.so( 5496): QQmlApplicationEngine failed to load component
W/libuntitled38_armeabi-v7a.so( 5496): qrc:/main.qml:1 module "QtQuick" plugin "qtquick2plugin" not found
W/libuntitled38_armeabi-v7a.so( 5496):
W/libuntitled38_armeabi-v7a.so( 5496): exit app 0
I/Zygote  (  130): Process 5496 exited cleanly (255)
I/ActivityManager(  472): Process org.qtproject.example.untitled38 (pid 5496) has died

Apparently, the qtquick2plugin library cannot be found. The apk contains a file

lib/armeabi-v7a/libqml_QtQuick.2_qtquick2plugin_armeabi-v7a.so

I assume that the postfix is due to the multi-archive feature of Qt Android 5.14. That same file inside a Qt 5.12.4 based apk is

lib/armeabi-v7a/libqml_QtQuick.2_libqtquick2plugin.so

Is the prior library name correct? If so, is the architecture-specific loading implemented correctly?
