odd zoom behaviour when using show_item parameter

[paulmaxus]

I've observed that when using the URL parameter show_item=x, the app zooms in on a node labeled y (x) instead of the node labeled x. I'm not familiar with the function levenSort, but it seems intuitively right to select the first item returned by the sort (line referenced below), so I'm wondering why I see the behaviour described above. The Levenshtein distance should be 0 for the exact match and I assumed sortedItems[0] would then return x.

@paulmaxus Could you please share an example that reproduces this issue? Thanks in advance!

[paulmaxus]

@neesjanvaneck Yes, of course. One example can be found in the citation network of journals example in the vosviewer docs. When I use the parameter physical review the app zooms in on biophysical reviews instead on for instance physical review b which should have the smaller distance.

--- EDIT

The better example is actually microbiology:
