When extracting some nodes in IGV and applying the difference selection by expanding it (button "Expand the difference selection"), I would have expected that it only shows me changes on the currently extracted nodes. However, it highlights (extracts) any changed nodes unrelated to my currently extracted nodes.

Example in selection_difference.xml:

1) Open the first graph and extract 697 If (before.png).
2) Click button "Expand the difference section".

Expectation: Same graph as before because nothing has changed for my extracted node 697 If (i.e. 697 If not removed and no input or output change).
Actual result: It shows me 3 newly added nodes in green that are unrelated to my previously extracted node 697 If (after.png).

Could this somehow be fixed to only show node changes that affect any of the currently extracted nodes (i.e. an extracted node is removed or any input or output of an extracted node changes)?
