Wikimedia Bugzilla is closed!

I am an avid Wikipedia reader on my Android phone. Several days ago, I noticed that the "Show/Hide" button of any section within an article would duplicate itself (i.e "Show/Hide/Show/Hide.......") indefinitely as that section was opened and closed, with the button itself growing into some sort of monstrosity.    I had considered that bug(which has apparently been eradicated with a new version of the software) to be only minimally annoying and even somewhat comical. However, at the same time the "Show/Hide button bug" appeared, I noticed two other much more annoying bugs.
    The first is that when I use my Android browser back button (specifically the hooked arrow on the face of the phone), instead of exiting the article and navigating to the previous browser page wikimobile will drag me back through the headings of every single section I had opened in that article. Before what I'm calling the "Show/Hide button bug", using the browser back button would simply take me back to the previous browser page which seems to make more sense to me. As it is, depending on the number of sections I have read I might have to hit the back button ten or fifteen times to get back to the previous article.
   The second, slightly less annoying bug I noticed regarding navigation seems to have begun occuring with the new version. After I've hit back ten or fifteen times in order to get to the previous article, I won't be in the same position in that article as I was before.
   The only frame of reference I have for calling out these two bugs is my previous experience with wikimobile - a single click meaning returning to the previous article in the same place I had been. I really enjoy reading Wikipedia, and I thank you for your time.
