Fix for application crashing
[Problem] Markup was needed to correctly parse each character for
text splitting operations
[Cause] Code assumes a text style per character. Clean solution will
require more work
[Solution] MarkupProcessing is enabled by default on TextInput.
TextView created by TextInput markup is inherited.
Scan for markup is no longer called and is forced by
MarkupProcessingEnabled flag.
