Does this issue occur when all extensions are disabled?: Yes

Anywhere in the whole workspace except Webview(there may be other places), the trackpad behavior is prohibited, including forward and backward, zoom, etc, Of course the zoom behavior via (ctrl++/--) is available. But in Webview area, forward, backward and zoom of trackpad, can be used.

It's strange to be able to step back here, It is easy to misoperate. I think it should probably be disabled here.

• VS Code Version: latest vscode.dev

Steps to Reproduce:

1. Open https://vscode.dev
2. Open a remote repo or any other folder.
3. Click a markdown file and Preview it, or any other operation that opens the webview
