Description of the Problem:
Trying to change the zoom via the magnifying glass tool by scrolling has stopped working a few month ago, usually I could click the drop-down menu for the percentile of zoom, then scroll the mousewheel to change it with ease, now even trying to use the mouse cursor to change it manually doesn't work, because the menu closes if the mouse leaves the set zoom strength. Reproduce the Problem:
Mouse-over the tool, click the drop-down menu, try scrolling/manually changing the zoom by cursor. Description of My Setup: Newest version of Firefox, as well as the newest version of Chrome have the same issue. No additional bars or add-ons. Cheers, Max
