Converting layer vector mask to regular path
I'm in Adobe Photoshop Version, 22.4.2 20210602.r.242, windows 10.
I have vector mask linked to a pixel layer (or a group, it's the same..).
This mask is made with a path that is not (yet) saved in the paths panel (for example, you can create one, attach it to the layer and then delete the path from the paths panel).
When I select the vector mask, the path is shown in the paths panel, italicized (like a working path).
When I drag the path to the "new path" icon, the path isn't saved as regular path. Nothing happens.
Even when I open the flyout menu and choose "save path", the path isn't saved. Nothing happens.
This used to work in Adobe Photoshop Version 20.0.10.
Why is it broken now??
