There was a problem hiding this comment.
I'm a little confused as to why this is buttons = 1 | 4 rather than 1 | 2 | 4?
0 MUST indicate no button is currently active.
1 MUST indicate the primary button of the device (in general, the left button or the only button on single-button devices, used to activate a user interface control or select text).
2 MUST indicate the secondary button (in general, the right button, often used to display a context menu), if present.
4 MUST indicate the auxiliary button (in general, the middle button, often combined with a mouse wheel).

The semantics of 'button' on events differs between PointerEvent and MouseEvent, whereas they are the same for 'buttons'. Furthermore, 'buttons' allows developers to determine when multiple buttons are pressed as the same time. https://w3c.github.io/pointerevents/#the-button-property
