This method can be used to change the content that is displayed in the tab bar, to the left of the tabs. The content is displayed left-aligned and will take as much space as needed to display the content that you set; it will not be implicitly clipped.
The parameter is a string that can contain escape sequences that change presentation.
It is recommended that you use wezterm.format to compose the string.
See window:set_right_status for examples.
