- the summary text is the list of permissions that the app has. It is dynamic, and when the list is long, setting the summary will expand the text view height and make the page launch looks janky. We cannot pre-set the summary to certain line, since the permissions list for each app is unknown beforehand. To avoid the jank, limit the summary to 1 line and truncate it if necessary.
