Mapped keys in embedded QML editor don't work

On Mac I have my "Home" and "End" keys mapped to take me to the beginning and end of a line of code respectively. When I open a QML file in Design mode and use the embedded "Text Editor", pressing the "Home" and "End" keys take me to the beginning and end of the document, like the default.

It would be nice if these preferences from the main code editor carried over into the embedded editor.
