Issue: When building a ship in either the VAB or the SPH, scrolling up, above the edge of the parts collection, or down, below the edge of the parts collection, the scrollbars change their size, rather than having their size remain constant. They appear to move further up or down, when there is more room for them to move. This issue appears in both the 32 bit version and the 64 bit version. The issue appears in the screenshots below.

The normal position of the scrollbar is the one located within the red circle.

However, if i try to scroll upwards, the edge of the scrollbar moves upwards, as if there are more parts and the edge has not been reached. This is visible in the screenshot below.

The same issue appears while scrolling down as well. The first screenshot below shows the normal position of the scrollbar and the second shows the edge moving when scrolling down.
