dialog tag
Why does the following code not work on OSX High Sierra 10.13.3 with Safari 11.0.3?
It works on all other browsers.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Dialog test</title>
</head>
<body>
<dialog>This text should not be displayed.</dialog>
<br />There should be only one line of text.
