Webview steals focus when I right click ont he Panel

[r3m0t]

Does this issue occur when all extensions are disabled?: N/a

• VS Code Version: 1.88.0
• OS Version: Windows

Steps to Reproduce:

1. Compile and install the webview sample - https://github.com/microsoft/vscode-extension-samples/blob/main/webview-sample/src/extension.ts
2. "Start cat coding session"
3. Open a split view with package.json on the left and the cat coding webview on the right
4. Show Panel and drag the Timeline into the panel, then click on the package.json
5. Right click an entry in the Timeline. Expected: timeline stays visible. Actual: timeline entries disappear and webview grabs focus.

Note: I have used git bisect to identify the cause is #206529

Note: sometimes this behaviour of focus going to the webview happens when you right click in the package.json as well.

Note: in the recording I have made some other changes, like removing the <img> tag, it is to reduce file size of the gif.
