Currently, VariablesView saves and restores its view state on every frame
change, including those triggered by simply selecting a different frame in
the same stack trace. However, while this is necessary in order to ensure
that things like selected formats and expanded nodes are preserved, it has
an undesired side effect, namely that it also overwrites the previous
saved values of those nodes. Consequently, after switching back to the
frame, it will no longer show the value changes that it did just before.
We need to detect this situation and not update the saved values in such a
circumstance, only doing so when the thread in question has actually
resumed execution. A simple solution may be to check if the frame is being
changed from one non-null value to another, as we normally clear the frame
when execution continues.
