Introduce a delay for key-press feedback on the Emoji palette

Currently key-press effect such as highlight and vibration
occur even when a user want to scroll the Emoji palette.
To mitigate this situation, this patch introduces a short delay
for key-press feedback on the Emoji palette.

This is not an ideal solution but should be better than now.
