* Fixes ComboBox text and list if the height is equal to one. End and Home navigate on text.
* Trying fix the all scenarios unit test.
* Removing unnecessary code.
* Avoiding the Collection was modified after the enumerator was instantiated exception.
* Also cover the IndexOfValue inside the lock.
* Disposing the DrawContent event.
* Increasing the time to test.
* Revert "Increasing the time to test."
This reverts commit b3c2ac871c.
* CharacterMap take more time to load.
