Description of the issue: Multiple instances of some extensions show up in Brave’s task manager

How can this issue be reproduced?

1. Open task manager
2. Sort by name

Expected result: Only one instance of each extension should be shown.

Brave Version: Version 1.37.72 Chromium: 99.0.4844.45 (Official Build) beta (64-bit)

@Dan33185 ,

**Chromium**

> **Multi-Process Model Background**

> To understand Chromium’s memory usage, let’s understand the multi-process model. Unlike other browsers, Chromium is divided into multiple processes. When Chromium starts up, it will initially have two processes. One process is the **browser process** which controls the main browser functionality, and the other is the initial **renderer process** , which runs the Blink rendering engine and JavaScript (V8). Each time you open a new tab in Chromium, you’ll likely get a new renderer process. With typical browsing, it is common to see 5-7 chrome.exe processes active. Further, if you utilize plugins, apps, or extensions, they may also execute within independent processes. All of Chromium’s processes, whether it is a browser process, a renderer process, or a plugin process, will show under the Task Manager as “chrome.exe”.

Ok, so it’s expected behavior? I just wanted to make sure some setting wasn’t wrong or something.
