Type: Bug

First of all, thank you for adding floating editor windows! Super useful feature that has already improved my productivity using VS code.

I'm experiencing a weird issue where I am unable to navigate to the first editor group (located in my original window) from a newly opened window. I am able to navigate to any other editor group, but just not the first one.

Steps to repro:

• Open vs code window with two editor groups (this is the "original window")
• Open new vscode window
• From the new window, press ctrl + 1 (workbench.action.focusFirstEditorGroup) to try to go to the first editor group in the original window
• Observe that nothing happens (expected to change focus to first editor group in the original window)
• From the new window, press ctrl + 2 (workbench.action.focusSecondEditorGroup) and observe that you can change focus to the second editor group as expected

Current workaround if I want to change focus to the first editor group from the new window is I do ctrl + 2 to go to the second editor group, and then I can press ctrl + 1 to focus on the first editor group. If I'm in the original window I have no issue switching between the first and any other editor group in that window
