Popover is great tool to work with and have many areas where it come very good in hand.
I do find a problem with users changing Zoom level either up or down and with working with Popovers they are not affected by the Zoom level at all
In my example down below I have a Report Engine that creates different Graphs that I show in a Popover. When I am in Zoom 100 things looks nice and the way I want them to be
When I set the Zoom level under 100 it still keeps same font size on the Popover, but everything else shrink like it supposed to do. Like below where I have Zoom level 50.
Same strange behaviour with Zoom level going up. In this example below 150.
I would the Popover to follow the Zoom level that I have for that window for all objects inside that Popover.
