title: ui.bootstrap tooltips stopped working
body: <p>Can figure out why would that happen. Other directives from ui.bootstrap work: <code>alert</code>, <code>progressbar</code>, etc. Yet popovers and tooltips for some reason stopped working. Anyone had this problem? I had a problem before - when for some reason default css rule for tooltip was <code>opacity:0</code>. But this time a bit different problem. It's not even adding tooltip related stuff to the DOM, as it used to be. </p>
  
  <p>Also I notice from controller of a view where tooltip being used I used to have access to stuff like <code>tt_title, tt_isOpen, tt_placement</code>, etc. Now suddenly I can't do that anymore.</p>
  
  <p>I'm suspecting something to do with browserify we're using. I noticed tooltips not working on my computer first, while on my colleague's they still would work, and then he removed bower files and node_modules, cleaned both npm and bower cache, and tooltips and popovers stopped working for him as well.</p>
  
  <p>I've tried adding <code>ui.bootstrap.tooltip</code> explicitly as a module dependency, although I already have <code>ui.bootstrap</code> listed. </p>
  
  <p>Please, if anyone had similar problems, and know possible solution, help me.</p>
