Option to disable right click contextual menu

### Steps to reproduce

1. I click the right mouse button on a message

### Outcome

#### What did you expect?

I expected the usual right click menu to appear that includes links to the page source and the DOM inspector. I use this a lot during developing and updating my custom CSS styles for Element Web:

#### What happened instead?

A new contextual menu appears whose functions can already be access by clicking the left mouse button on the `...` in the corner.
