Mouse down on Increment/Decrement buttons stops number change in BitDatePicker

[Cyrus-Sushiant]

There seems to be an issue with the BitDatePicker component's increment and decrement buttons. When clicking and holding down the mouse button on either the increase or decrease buttons, and then slightly moving the mouse (without leaving the button area), the number change operation stops and does not resume.

Steps to Reproduce

1. Click and hold down the mouse button on the 'increase' or 'decrease' button within the BitDatePicker component.
2. Without releasing the mouse button, slightly move the mouse while still over the button.
3. Observe that the number stops changing and does not continue even if the mouse is still down.
