TopBar Sticky vs Fixed
We see a lot when people are using TopBar that if they have the TopBar at the top of their web page, they change the position setting (which is set to Static by default) to Sticky.
If you have the TopBar as your top most stack, we suggest that you NOT use the Sticky setting, but instead choose the Fixed position. The reason for this is when the setting is set to Sticky, the stack has to be pulled out of the flow and stick to the top when it goes off the top.
