I'm translating some of my old HTAs from Quirks to IE9 standards. However, it seems that modal and modeless dialogs opened by HTA don't support IE9 standards mode.
Test dialog:
<!DOCTYPE html>
<html>
<head>
<title>TestDialog</title>
<meta http-equiv="x-ua-compatible" content="ie=9" />
</head>
<body>
<svg>
<circle cx="100" cy="100" r="50" fill="#0f0" />
</svg>
</body>
</html>
In the HTA main page:
<button onclick="showModalDialog(...)">Modal</button>
<button onclick="showModelessDialog(...)">Modeless</button>
When opening TestDialog from HTA, it's empty. If the main page is a regular html-document, the green circle appears in the dialog. When opening from HTA, there's no difference if the dialog file itself were htm or hta.
I've also tested addEventListener() but it also won't work in dialogs.
So, can I "force" dialogs to support IE9 standards when opening from HTA?
EDIT
It seems that modal and modeless dialogs opened from HTA are on the level of IE8. This same happens when using IE10 in Windows7.
