[reg 5.4->5.5] ListView behaves incorrect after flick: current item becomes hidden and keyboard scrolling buggy

Problem: (see attached QML and animated GIF)

• Setup a ListView which can be controlled via keyboard arrows keys
• Use two finger flick and move visible area a few pixel
• Now try to navigate with cursor keys
• Instead of smoothly scrolling at bounds the current item gets invisible

Note:

• The problem does not occur when I press the touchpad and drag
• If the problem occurs and I press touchpad, the problem disappears (of course that's not a workaround for a user)
• I also noticed that onMovementEnded is not emitted when using the touchpad the described way.
