Open path, delete lines in vector tools / pen tool

Hi!

I flattened an icon so I only have one path to deal with. Now the path is closed for some reason and I would like to open it but I am not quite sure how I can delete a side / open the path.

For example the line marked red here I would like to be gone:

But I am not quite sure how to achieve this. Many thanks in advance!

This seems to be a bug, could you open an issue in our GitHub repository? GitHub - penpot/penpot: Penpot: The open-source design platform for Product teams that need scalable collaboration. · GitHub

It would help us if you could attach the icon and tell us if this happens only with the WebGL render active. Thanks!!
