If the component description text in the installer component tree view is long, there is no other way for the user to see more text than resize the window. Even when resizing, the user does not know if the description text is shown completely. 

Could the UI control used to show the description changed to allow scrolling. Also an indicator that there is more text would be useful. 

For example, in the Qt WebEngine description, it's not clear, why the text is cut (description incomplete) below. Is it a bug or is there more text readable somehow? In the more complete description, the user still cannot be sure, if all the text is shown.
