Messages are supposed to have a right-click menu. In browser, right-clicking a message does nothing, unless text is selected, in which case it opens the UA text selection menu.
This is probably done because the Electron app reimplements the selected-text menu as well to allow copying, but instead of opening the custom context menu when right clicking without selection and opening the browser context menu when right clicking with selection, the message context menu is just disabled when not in an 'embedded' environment.
This bug has been there since 2015, and is yet unfixed.
