The subject here is marked as icl, but the code seems to all platforms

Sorry, my mistake. Will update it accordingly.
But also I didn't check spec yet on this particular case
The spec only mentions that the result lines should be greater than the
level 0 result lines.
But this change is in line with the code comment for result blocks, to
make sure that the result lines calculated is in correspondence with the
result blocks.

As the result blocks for WM1-WM7 are always kept higher than the
level below the present level, make sure result lines are also higher
than the level below for WM1-WM7.
