qdoc does not parse .pragma lines in javascript files

Using for example the module QtQuick.Controls

$ make html_docs

in qtquickcontrols/src/controls

return the errors:

qdoc: warning: Unable to parse JavaScript: "Syntax error" at line 41, column 1
qdoc: warning: Unable to parse JavaScript: "Syntax error" at line 41, column 1
qdoc: warning: Unable to parse JavaScript: "Syntax error" at line 41, column 1
qdoc: warning: Unable to parse JavaScript: "Syntax error" at line 41, column 1

It seems those errors are caused by UI.js files located under
qtquickcontrols/examples/quick/controls/gallery:

• qml
• qml/+android
• qml/+osx
• qml/+ios

which have .pragma library line 41 (would be nice to have the path to the file causing the problem in the warning output )
