I am having a problem with the inline toolbar editor dropping to the bottom on drag if I am scrolled down on a page. It works just fine if I am scrolled all the way to the top. Once I scroll down whatever the offset calculations are seem to be off and the toolbar drops instantly to the bottom.
The same offset problem is happening to the drop-down menus when scrolled down on both editors, not just the inline. To reproduce be scrolled to the top with a focus on the editor and open a drop down. Then scroll down a little and open the same drop down again. The drop-down appears to render in the same location the toolbar was in before you scrolled.
