Fix crash during cursor moving on BiDi text

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.
