    Looks like jQuery Mobile might not be compatible with jQuery Core 3. Page works when you downgrade to version 2.2.4.

    This also could be happening when another version of JQuery is loaded over the base version by some other modules and then due to compatibility issues jquery.mobile.custom.js starts getting undefined event properties of the mouse.

    Please check version compatibiltiy.
