[dagatsoin]

Issue

Current behavior
User cannot press button again just after a long press. The user mush do a double tap as a workaround.
This can be reproducted on the current test app on the long press button test on web mobile:
1- do a long press, the "Long press count" increases
2- do a press, the "Press count" does not change
3- do a press again, the "Press count" increases.

Expected behavior
1- do a long press, the "Long press count" should increase
2- do a press, the "Press count" should increase

Fix

This PR does the following.

• reflect the behavior of desktop: the onMouseUp event after a longPress is canceled and the _ignoreClick flag is reset.

QA

1- do a long press, the "Long press count" should increase
2- do a press, the "Press count" should increase
