[Edit] I made a little research and it seems it's vscode's fault, not the extension.
As of the november 2023 update, vscode started allowing for auxiliary floating windows to be created from dragging any tabs out of the main editor. But doing so with the current version of REST Client renders an error when running the requests that says "This type of editor cannot be opened in other windows yet." Screenshot bellow.
So I thought the extension author would like to know about it. Personally, I think it would be a really nice addition to the tool if it supported child windows.
