+        You will see empty rectangles unless this browser implementes basic support for the &lt;permission&gt;&nbsp;element. In Chrome M120 or later, follow these instructions to enable experimental support:

+          <li>Shut down the browser process.</li>
+          <li>
+            Restart the browser with these command line flags:
+            <pre>--enable-blink-features=PermissionElement --enable-features=PermissionElement</pre>
+          </li>
+          <li>
+            Ensure the flags actually took effect by verifying they appear on:
