The following note is not correct anymore:

vscode-js-debug/src/build/strings.ts

Lines 35 to 36 in fcc2ab2

	'extensionHost.launch.debugWebviews':
	'Configures whether we should try to attach to webviews in the launched VS Code instance. **Note:** at the moment this requires the setting `"webview.experimental.useIframes": true` to work properly, and will only work in desktop VS Code.',

'Configures whether we should try to attach to webviews in the launched VS Code instance. Note: at the moment this requires the setting "webview.experimental.useIframes": true to work properly, and will only work in desktop VS Code.'

Using iframes for webviews is default now.
