Make a recording in the performance tool.  Then, click on a marker.
Now, make the browser window lose focus.  I can do this by moving the
mouse to another window (this is Gnome 3 with "sloppy focus" mode).
At this point the highlighting of the marker in the waterfall view
disappears, and the marker details view goes completely blank.
Moving the mouse back into the browser window makes these reappear.
Working on consolidating a react-based tree widget that suits the Performance tool's needs. This bug happens because of the way we track selected items inside the AbstractTreeItem, using :focus instead of keeping a track of our own "highlighted" item, and using XUL event dispatchers to maintain/navigate selection. Although elegant, in hindsight this was a terrible idea because of XUL. As we move to a different widget this problem will disappear.
