Hi,

For PointerEvent properties clientX and clientY values are long integer instead of double in Safari IOS.

PEP as a Polyfill should handle this ? No ?

PointerEvent clientX and clientY came from MouseEvent inheritance.

Mozilla Developer Network (MDN) docs definitions:

• clientX

  Pointer.clientXEvent => MouseEvent.clientX Read only

  The X coordinate of the mouse pointer in local (DOM content) coordinates.
  The clientX read-only property of the MouseEvent interface provides the horizontal coordinate within the application’s client area at which the event occurred (as opposed to the coordinate within the page).
  A double floating point value, as redefined by the CSSOM View Module. Originally, this property was defined as a long integer. See the “Browser compatibility” section for details.

• clientY

  PointerEvent.clientY => MouseEvent.clientY Read only

  The Y coordinate of the mouse pointer in local (DOM content) coordinates.
  The clientY read-only property of the MouseEvent interface provides the vertical coordinate within the application’s client area at which the event occurred (as opposed to the coordinate within the page).
  A double floating point value, as redefined by the CSSOM View Module. Originally, this property was defined as a long integer. See the “Browser compatibility” section for details.
