Leaving this open until a new Tauri release as Mouse 4 and 5 are not supported for Linux based on mdn:

On Linux (GTK), the 4th button and the 5th button are not supported. In addition, a [mouseup](https://developer.mozilla.org/en-US/docs/Web/API/Element/mouseup_event) event always includes the releasing button information in the buttons* value.
