You cannot swap items in inventory using touchscreen mode

When you try to swap between items in inventory it won't work if you have touchscreen enabled.

I think it's because of mouse down, mouse up events. The swap function will not start with drag & drop movement/mouse triggers

This is a bug of jira that keeps the image I've uploaded in the past bug report and there's not any way to delete it from the tickets.
