title: WebView text too small cannot make bigger XForms (4.8)
body: <p>wondering if anyone can help, the text on the webView is too small, I have an HTML that I have NO control over.
  How can I increase the size?</p>
  <p>I have tried <a href="https://stackoverflow.com/questions/61114274/xamarin-forms-webview-content-default-size-is-too-small/61114750#61114750">Xamarin forms: Webview content default size is too small</a></p>
  <p>but did not work for me as the page does not load at all.</p>
  <p>Is this a bug?
  Am I missing something?
  Any suggestions</p>
