​You can use ALT+click on an arrow to expand a​ whole subtree. However,
because after a certain depth we start incrementally loading sub-trees,
those incrementally loaded subtrees will not be auto-expanded. In general,
the dominator trees are too large to eagerly display in the UI; there is an
item in the tree for every node in the heap graph that we snapshot'd.

That is a pretty unfortunate screenshot. ​We have a bug in flight to ensure
that the columns are wide enough​:

If we can always ensure that the minimum cell size in the table is large
enough to display the number contained within, then I'm not convinced we
need resizing. Perhaps we can take this discussion to that bug, or a new
one?
