Can't make Gtk.TextView () fill whole parent Gtk.Box

Question

Can't make Gtk.TextView () hexpand. Only expands to like 2/3 of parent and wraps words too early.

A lovely application you built here, I particularly like the native indicator!

Looking into your Application.css:

.command_wrapper {  
    background-color: #fdf6e3;  
    border-radius: 3px;  
    box-shadow: 0 1px 1px rgba(0, 0, 0, 0.12), 0 1px 2px rgba(0, 0, 0, 0.20);  
    padding: 5px;  
    padding-right: 190px; 
}

In ProcessInfoView.vala (58:59), you are applying the 'command_wrapper' class to the command_wrapper Box widget:

var command_wrapper = new Gtk.Box(Gtk.Orientation.VERTICAL, 0);
command_wrapper.get_style_context ().add_class ("command_wrapper");

Commenting the padding-right: 190px line will result in the TextBox 'expanding' horizontally:

Also, I believe it is worth mentioning that in dark mode, the text in the TextBox is unreadable:
