enable the text layout's cache where it is seems to be missed

e.g. in QStaticText, the data is used just to get the line's y-position
and re-calculates just after the loop to determine the bounding rect and to draw the text;

in QWidgetLineControl, the data re-calculated over and over while the result
is seems to remain the same; probably the caching is needed here too
