Secondary window in browser close/reopen has odd behaviour

[MatthewKhouzam]

Bug Description:

When one opens a secondary window, then closes it, in the browser, they can then restore the last closed window. This is typically by pressing the ctrl-shift-n combo or something equivalent in other OSes will re-open a closed window. That window is now "useless".

Steps to Reproduce:

1. Open a terminal from theia browser.
2. Make it go to a secondary window
3. close that window
4. re-open it with ctrl-shift-n

See video for an illustration.

Additional Information

• Operating System: Linux
• Theia Version: 1.38 and 1.41

I was not aware of this key combination! good catch!

Our approach is to copy the html nodes from the main to the secondary window. We lose all that content when we close the window. I don't see a way to recover the secondary window content, so maybe the "solution" is to disable the reopening of the windows?
