Should jump to splitted window instead of open a new window

Type: Bug

When you have window a and window b opened, split window b to another panel, now you have window a in left, window b in right。window a has a method, it calls methodB that is defined in window b. Press F12 to go to the declaration of methodB, vscode will open a new copy of window b, instead of jump to the opened window b.
