Description

The Command-Line value in about:version often contains redundancies.

1. Navigate to about:version

Actual result:

Redundancies in Command-Line value.

1.3.115 (current stable) contains the following redundancies:

@jonathansampson
Can you try again with 1.7.92? Still an issue?

[jonathansampson]

@rebron I still see redundancies:

It is tied to "relaunch" because it will inherit the args before relaunching
STR:

1. Go to brave://flags/ and randomly change something and change back to trigger relaunch prompt

2. Click Relaunch button
3. After relaunch go to brave://version/
