Clicking parent branch doesn't zoom out

[eharkins]

Current Behavior
When clicking on a branch in auspice, you zoom into view a clade or specific part of the tree. When @BryanTegomoh tried recently to click on the root of the clade in view (hover shows "click to zoom out to parent clade"), nothing changed / the tree did not zoom out.

Expected behavior
Clicking on the root of a zoomed in auspice view (where it says "click to zoom out to parent clade" as you hover) should zoom out to the parent clade.

How to reproduce
Still need to get in touch with Bryan about reproducing this. I think it's related to his browser which is different from mine.

Possible solution
Adding some animation or other type of support for the Mircrosoft Edge browser to allow this feature to work in that browser.
