Does the IGGraphEditor command fail to return the modified embedding?

[lichengzhang1]

Describe the bug I would like to modify the graph embedding below (the original embedding is Tutte embedding). to make it more experiment-friendly. So I used the command IGGraphEditor but strangely, when I change its embedding and I press the Shift-Enter keys, the layout remains the same as before.

To Reproduce

I've noticed that when I move (or just click) the four vertices (or any one of them) on the external face, and then press Shift-Enter, the embedding of the graph adjusts accordingly. Otherwise, it keeps the original embedding. This is quite strange.

[szhorvat]

Can you have a look at this @kubaPod ?

[kubaPod]

@szhorvat Should not happen but I can reproduce it. Not 100% why it does so it is probably something deeper than my code, will investigate more next week. I can't reproduce it on most recent dev branch so the next, hopefully September, version should fix this.

@lichengzhang1 Yes, selecting a vertex is enough to fix it.

[kubaPod]

@szhorvat @lichengzhang1 I think it is already fixed in the editor branch
