TinyMCE inside hidden div are not displayed as enabled when we put the div visible

Question

I am having an issue with tinyMCE (WYSIWYG editor). I am actually adding the textarea inside a HTML element like a DIV which is currently having the style attribute "display:none".

When I am changing the DIV display style to visible the tinyMCE editor is shown as disabled.

Important Note: The setting which is causing the issue is the "auto_resize" option. This is the only option that I turn on/off that make the tinyMCE editor goes in edit or read-only mode.

Here's my code:

tinyMCE.init({
 mode: "specific_textareas",
    editor_selector: /(RichTextArea)/, 
    theme: "advanced",
    auto_reset_designmode: true,
    auto_resize:true,
    theme_advanced_buttons1: "bold,italic,underline,strikethrough,|,fontselect,fontsizeselect,|,forecolor,backcolor,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,justifyfull",
    theme_advanced_buttons2: "",
    theme_advanced_buttons3: "",
    theme_advanced_buttons4: "",
    theme_advanced_more_colors: 0,
    theme_advanced_toolbar_location: "external",
    theme_advanced_toolbar_align: "left"
});

...

<a href="#" onclick='document.getElementById("myHiddenDiv").style.display = "block"; return false;'>Show WYSIWYG</a><br/>
<div id="myHiddenDiv" style="display:none">
    <!-- Gets replaced with TinyMCE, remember HTML in a textarea should be encoded -->
    <textarea class="RichTextArea" id="elm1" name="elm1" rows="15" cols="80" style="width: 80%">
     &lt;p&gt;This is the first paragraph.&lt;/p&gt;
     &lt;p&gt;This is the second paragraph.&lt;/p&gt;
     &lt;p&gt;This is the third paragraph.&lt;/p&gt;
    </textarea>
</div>

I would like to know if anyone has an idea of how to fix that issue?

Try calling tinyMCE.init(...) after you unhide the containing div.
