Description Matt Baker 2017-10-15 19:55:00 PDT
Scrolling the editor while debugging shouldn't trigger popovers.

After one or more mousewheel events, a single mousemove event is fired. This causes the CodeMirrorTokenTrackingController to display a popover if a token comes to rest under the cursor. This can be *extremely* distracting when reading/scrolling code while the debugger is paused.

It also causes a situation where popovers can appear while the mouse cursor is hidden.

Steps to Reproduce:
1. Pause in the debugger
2. Cursor around in the editor using the arrow keys
  => The mouse cursor disappears
3. Scroll the editor using the trackpad/mouse wheel, a few lines at a time
  => Popover eventually appears once hidden cursor comes to rest over a token
