Double click in WebGL game window causes issues on EDGE

Hi, I have this Unity WebGL that builds just fine (using 2018.2) and works well in Chrome but I am having issues on EDGE (on PC).

The game requires double clicks, and it seems that the event is passed to the webpage or something, because after a double click in the game frame, my next click and drag inside the game frame actually drags the whole frame.
I’m using an unmodified HTML page generated by the Unity build.

Is there any way I can prevent this odd behavior?

As a reference, here is the HTML:

Unity WebGL Player | MyGame
MyGame

Come on, nobody but me has this problem on EDGE? :slight_smile:
The browser catching mouse events eratically?
