[iOS 15.5] Incorrect events on canvas long press

In the following simple scenario I created there are different events fired when using the plugin versus not using this plugin. Here is the following code to reproduce - I've moved everything related to Cordova to a single html file: This basically draws the events that are captured from the canvas to a ul element. When not using the plugin the only event that are fired when using long click are: touchstart and touchend When using this plugin there are more event related to mouse operations which shouldn't be fired: touchstart touchend mousemove mousedown mouseup

I think this is new, maybe in 15.4 or so as I think this was not present in 15.0. It happens only on "long click" and not on "regular click". Please let me know how I can help further debug this issue.
