Capture back&forward navigation mouse buttons and prevent navigation when editing script

[AlCalzone]

Is your feature request related to a problem? Please describe.
VSCode has the ability to navigate back and forth between recently edited code locations using the side buttons of the mouse. Doing this in the JS adapter is dangerous though as it will cause the browser to navigate and lose all edits made since the last save.

Describe the solution you'd like
Prevent navigation using the mouse buttons or at least ask the user if they want to navigate away.

Describe alternatives you've considered
None

Additional context
Losing half an hour worth of work because of one accidental button press is not nice.
