Open folder not reused window with multi root workspace

[Thaina]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.90.1, maybe since we have multi-root workspace system
• OS Version: Windows 10

Steps to Reproduce:

1. Open some folder in vscode
2. Add some more folders into workspace and it would become workspace
3. Open folder that already opened in workspace with cli code <opened folder>

Result behaviour is, it will just open a new window with a folder that already opened in another window workspace

With -r option it then trying to close the last active window and reopen into only that folder
With -a it then try to create workspace if that folder is not yet opened
Drop the folder and only open the file with -g then it might open a last active window that not a window that actually contain the file
All of these are not ideal

I wish that if there is any workspace already contain that folder it should just make that window become active and use it. But if there is none then it should open new window normally. This should be default behaviour of vscode without any flag

If it can't be default behaviour then I would like to propose a new flag, such as --reused-if-exist/-re

Also sometimes we would like to open folder to existing workspace, but specifically to workspace that already contain folder we known. And so I would like to also propose that there could be a flag --add-to <mainfolder> which will check that, if the mainfolder already opened in any window, it would use that window to create workspace

Or maybe let it that, when we open code with list of folder into workspace, if the first folder in the list already opened, vscode will use that folder as the main, choose opened window as a base, and open workspace in that window

Is this behaviour possible?

It seem like this might be the problem

vscode/src/vs/platform/windows/electron-main/windowsFinder.ts

Lines 44 to 52 in 35ac2d0

	export function findWindowOnWorkspaceOrFolder(windows: ICodeWindow[], folderOrWorkspaceConfigUri: URI): ICodeWindow | undefined {
	for (const window of windows) {
	// check for workspace config path
	if (isWorkspaceIdentifier(window.openedWorkspace) && extUriBiasedIgnorePathCase.isEqual(window.openedWorkspace.configPath, folderOrWorkspaceConfigUri)) {
	return window;
	}

The code here was tested only if the workspace itself has the same root as the folder it try to opened but not ask for the opened folder inside workspace unlike findWindowOnFile above
