Comment 2 for bug 1566373

Something (I don’t know what yet) appears to be briefly stealing focus from the webview when the "Compose" button is tapped.

I monitor changes to Window.activeFocusItem and I’m seeing it change twice, although the value of the activeFocusItem is always the webview (if activeFocusItemChanged is emitted, there must be another item that is getting the active focus in between though).

I cannot reproduce the issue with a plain oxide WebView inside a MainView, so there is something that is webbrowser-app/webapp-container specific.
