Description

Checking the Hidden on Startup option in tree-view settings doesn't prevent the file pane from showing up on startup.

Steps to Reproduce

Check Hidden on Startup, quit Atom, and try to open a text file with Atom.

Expected behavior:

Project pane stays hidden on startup

Actual behavior:

Project pane shows up after a second or so

Reproduces how often:

Every startup

Versions

I'm using macOS 12.2.1, and atom --version gives

Atom    : 1.60.0
Electron: 9.4.4
Chrome  : 83.0.4103.122
Node    : 12.14.1

apm --version gives

apm  2.6.2
npm  6.14.13
node 12.14.1 x64
atom 1.60.0
python 3.10.0
git 2.30.1

For me Hidden on Startup seems to be ignored in case there is no project folders added to the Tree View.

For me Hidden on Startup seems to work only in case Atom reopens with the Settings tab (still) open.

I'm using Fedora 36 KDE. atom --version:

Atom    : 1.60.0
Electron: 9.4.4
Chrome  : 83.0.4103.122
Node    : 12.14.1

apm --version:

apm  2.6.2
npm  6.14.13
node 12.14.1 x64
atom 1.60.0
python 3.10.4
git 2.36.0

There is a workaround using a script in this comment.
