Normally that's not a problem, provided the vertical boundaries got detected correctly. On the next tab in debugging mode, you would see those blue lines extended up to the vertical boundaries. If the vertical boundaries got detected incorrectly, or if it still somehow produces a trapezoid, I can take a look if you provide me with the source scan.
BTW, multicolumn text is not supported by this algorithm. The reason it works in this particular case is that text lines in your columns are aligned and close together.
