Closing Application Output tab of disconnected Android device takes two attempts

Steps to reproduce

1. Open e.g. "swipetoremove" example from Qt Quick Controls 2
2. Start application on Android device
3. Disconnect Android device
4. Click 'X' on Application Output tab (opens the "Application Still Running" dialog)
5. Click 'Force Quit'

Expected outcome

Tab is closed (as in Qt Creator 4.3.1)

Actual outcome

Nothing happens. Second click on 'X' closes tab (without any dialog) and prints

SOFT ASSERT: "state == RunControlState::Stopped || state == RunControlState::Initialized" in file /work/build/qt-creator/src/plugins/projectexplorer/runconfiguration.cpp, line 662
QProcess: Destroyed while process ("/opt/android-sdk/platform-tools/adb") is still running.

Notes

Also clicking on the "Stop Running Program" button (the little red square) does nothing (both in 4.3.1 and 4.4.0-beta1). I don't if this is expected, but it doesn't seem very intuitive.
