Interrupting QML engine never interrupts

• create dummy QML application
• start debugging
• switch to QML engine ("QML for <name>")
• press interrupt button

Actual:

• the debugger prints "Waiting for JavaScript engine to interrupt on next statement"
• all debugger actions are disabled
• it never stops, even when adding a MouseArea and putting some statements in its onClicked: handler, and tapping it.

Expected:

• it should stop at some point (maybe I miss something there...)
• it seems wrong that all actions are disabled, it should at least be possible to kill the application (without switching explicitly to the C++ engine), and probably be possible to get out of the "waiting" state. If a QML breakpoint is hit while "waiting" it recovers though, so that's not too bad
