Description

I usually have multiple Atom windows open simultaneously. Often when I restart my Atom session, the first window remembers that I had the Tree View, Git Tab and Github Tab open, but the others don't.

Steps to Reproduce

Have multiple Atom windows open.
Ensure each window has the Tree View, Git Tab and Github Tab open.
Restart Atom: either perform an update of a plugin and use the Restart button, or press CTRL-Q to quit and launch Atom again.
Wait for Atom to fully load/initialise.

Expected behavior:

I expect all Atom windows to open with an active Tree View, Git Tab and Github Tab

Actual behavior:

Atom opens, the first window that's launched opens with active Tree View, Git and Github tabs, but the other windows have the Tree View, Git and Github tabs deactivated.

Reproduces how often:

Intermittently.

Additional information:

I can't reproduce it now. However, I normally don't relaunch Atom unless it's for an update to one or more of my plugins, or because a new Atom version has been installed through my package manager, neither of which currently apply. I don't rule out it might be related to the updates. I'll try to remember to record my screen next time I have Atom updates.
