[NTG-context] focus=standard not respected

In the following example the page focus jumps back to »fit« after clicking on the footnote number after »Foo«, although »focus=standard« is set. \setupinteraction [state=start, focus=standard] \starttext Foo \startfootnote Bar \stopfootnote \stoptext How to respect the users scaling factor? BTW: Is there a particular reason why »focus=fit« is the default? Why should the page scaling change because the user clicked on a hyperlink? Marco
