Screen shots with tree breakage samples

I tried it on a benchmark just because it generates lots of profiling data. Any
other page with JavaScript can be actually used.

I observe the following problems:

- in Heavy view, after focusing on a non-expanded function node and then
restoring back, its children disappear from view (see the first two samples on
screen shots);
- in Tree view, after focusing on a non-expanded function node and then
restoring back, node completely disappears.
