Fix crash during cursor moving on BiDi text

The crash was introduced by Ib66ef392c19c937718e7101f6d48fac3abe51ad0
The root cause of the crashing is requesting out-of-line access for the
horizontal width. This invalid access is silently ignored by
TextLine#measure() method but new implementation end up with out of
bounds access.

To makes behavior as old implementation, calling getHorizontal instead
of accessing measured result array.
