Sorting a list view causes the Tags column to disappear and become unusable until the list is refreshed.
Steps to Reproduce
Go to /incident_list.do.
Add the Tags column.
Add some tags to some records.
Sort the Number column several times.
Note that the tags disappear from the Tags column. The tags will reappear when the incident list is refreshed.
This problem is fixed since the Istanbul release, but only using List v2. No fix exists on List v3, which has been decided to not further develop or support in the current releases.
If the tags are not visible after sorting, refreshing the list or clearing the instance cache should resolve the issue.
