A DESCRIPTION OF THE PROBLEM :
When TextField has right-to-left orientation and it has keyboard focus, pressing left-arrow and right-arrow keys on keyboard does not move the cursor within the contents of the TextField. Pressing up-arrow moves cursor to start of text. Pressing down-arrow moves cursor to end of text. Pressing left-arrow or right-arrow keys does not move cursor at all.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a JavaFX application. Create a TextField control. Add text to the TextField. Set the TextField orientation to right-to-left. Add the TextField to a Scene. Give the TextField keyboard focus. Press left-arrow or right-arrow keys on keyboard. Cursor does not move.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Pressing left-arrow key should move cursor by one character. Similarly when pressing right-arrow key. This is the behavior when the orientation of the TextField is left-to-right.
ACTUAL -
Cursor does not move when pressing left-arrow key or right-arrow key.
