Mouse input in web

[porky11]

When clicking the right mouse button in a web application (wasm), the default right mouse button event of the browser (some menu) overrides the right mouse button event of my application.

You will probably need the following for your canvas:

<canvas oncontextmenu="return false;"></canvas>

see here for more options (you can utilize those using web_sys on the HtmlCanvasElement that winit created).
