Repro steps:

• Start the webview example app on Android with TalkBack on.
• Open the "Navigation Delegate example" from the meatballs menu (this is not a necessary steps, but it's probably easier to debug with a simpler page loaded)
• Invoke the "refresh" button.
• Try to use touch exploration to select one of the links in the page(it doesn't work).

Note that after changing the currently focused node (swiping left/right or using touch exploration to select one of the Flutter buttons) touch exploration for the webview works again.
