Fix the miss-alignment of sections by few pixels

From tests, it is found that sections alignment go wrong by
a few pixels even after correct height is set. Browser does not
use that exact value probably due to rounding and other unknown
factors.

This patch tries to fix it by adjusting the height till an agreable
height is found
