incorrect implicitWidth on centered element causes invalid text wrapping

When I set the width of a Text item to implicitWidth (i.e. Layout.maximumWidth: implicitWidth) and center it in a ColumnLayout, the text will sometimes wrap even though there is plenty of space.  Changing the width of the column (by dynamically resizing the window) causes the problem to come and go; it goes on/off for each pixel that the width changes.  If I align the Text item to either left or right instead of center, then the problem goes away.  Adding one to the Text width (i.e. Layout.maximumWidth: implicitWidth + 1) alleviates the problem so that the wrapping does not occur, which leads me to believe that it's a bad calculation of implicitWidth.

Because I can make it go away by adding one and because it goes on/off for each pixel the column width changes, my hunch is that there's a division by 2 round-off error related to centering.
