macdeployqt does not deploy QtQuick.Controls 1 and 2 plugins

When using mixed QtQuick.Controls 1 and 2, macdeployqt does not properly deploy both versions.

I get the runtime error:

module "QtQuick.Controls" version 1.4 is not installed

In my case:
***.app/Contents/Resources/qml/QtQuick/Controls.2/ contains the correct content
But:
***.app/Contents/Resources/qml/QtQuick/Controls/ does not contain the expected content from (QtInstallDir)/(compiler)/qml/QtQuick/Controls :

• ***.app/Contents/Resources/qml/QtQuick/Controls/
  • Material (copied from Controls.2)
  • Private (copied from Controls)
  • Styles (copied from Controls)
  • Universal (copied from Controls.2)
  • NO FILES (??)

When I manually copy all contents from (QtInstallDir)/(compiler)/qml/QtQuick/Controls to my application package: ***.app/Contents/Resources/qml/QtQuick/Controls/, all works fine.

I have the idea it is related to the windeployqt bug which has been solved before: QTBUG-54021, where the origin of the problem is that both Controls 1 & 2 have the same module names (and thus they should be matched on classname instead)
