Enabling Tor mode by default (under Properties) opens 2 windows

[ShadowOne333]

Description

Adding the --tor argument at the end of the "Target" box opens up two Brave Private Tor windows, instead of just one,
This behaviour is also mirrored if trying to add the --tor argument in Brave's pinned icon in the Taskbar.

Steps to Reproduce

1. Right click on the Brave browser's icon, either under Desktop or the pinned icon on Taskbar (Windows 10)
2. Select "Properties"
3. Add the --tor argument at the end of the path found in the Shortcut tab inside the target box. Ex: "C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe" --tor
4. Apply and save the changes
5. Try opening up Brave with Private+Tor by double clicking on the Desktop icon, or clicking on the pinned icon on the Taskbar.
6. Brave will open up 2 windows instead of only one. (Tor and Tor 2)

Expected result:

Opening Brave after making the change to open Tor mode by default should open up only one window.

Reproduces how often:

Easily reproduced each time one tries to open Brave after making the changes, both by clicking on the Desktop icon and by clicking on the pinned icon in Taskbar.

Other Additional Information:

Using the --incognito argument instead of --tor opens up a single window, as expected.
It's only the --tor argument that causes the issue.

can confirm this happens with the current linux version, too. To add to the story, this behavior seems to be new since I am 100% sure that previously only one window was opened when using the --tor option. The --incognito option continues to work properly btw.

brave-browser --version output:
Brave Browser 99.1.36.111

I'd also like to ask if there's a way to automatically start Brave in either Incognito or Tor mode in Linux, as it doesn't have a way to modify the argument given to it when opening it from the Activities overview or as an icon in favorites/Applications list.

I can confirm this also happens in MacOS when opening from the terminal
$ ./Brave\ Browser.app/Contents/MacOS/Brave\ Browser --tor
