The following code produces a textbackground whose background color enters into the "itemize label" area on the second (and succeeding) lines of the paragraph.  I would appreciate advice on fixing this.

Thanks,

Troy Henderson

\setuppapersize[letter,landscape][letter,landscape]

\definetextbackground[foo][
    state=start,
    location=paragraph,
    background=color,
    backgroundcolor={0.875,0.875,0.875},
    frame=off
]

\starttext
    \startcolumns[n=2,rule=on]
        \startitemize[n,2*broad]
            \item Here is my first item
                \starttextbackground[foo]
                    Here is some long text that demonstrates how the background color is wrong on the second line and all successive lines of this paragraph.
                \stoptextbackground
            \item Here is my second item
        \stopitemize
    \stopcolumns
\stoptext
