Click event doesn't get fired when clicking on button text, but releasing outside the text (however, still inside the button).
Steps to reproduce:
1. Press left mouse button while the cursor is over button text
2. Move the cursor (while pressed) to an area of the button without text
3. Release the mouse button
Events mousedown and mouseup fire. click — does not.
Same as bug 39620?
