Allow nodes to save connections while setting preview

[Tomatiy]

Sooo, if you have node with configurable amount of connections - if you will try to decrease them just for preview purposes, but will not change them, - as result you will receive node with same amount of inputs, but all of them will lost connected wires

I wish to keep them connected, bruh

I think a separate “preview range” would be cool. So you can sift through a subset!

It does seem logical to only perform the disconnection action on final commit instead of during the preview process to prevent this issue!
