Sets the tooltip for this tray icon.
Platform-specific:
Linux: The title will not be shown unless there is an icon as well. The title is useful for numerical and other frequently updated information. In general, it shouldn't be shown unless a user requests it as it can take up a significant amount of space on the user's panel. This may not be shown in all visualizations.
Windows: Unsupported
