Same here. To shorten the code a little bit:
<textarea style="display: none;" id="ta" name="test" cols="40" rows="10"></textarea>
<a href="javascript:alert(document.getElementById('ta').selectionStart);">ClickMe</a>
If I click on the link I get the following exception:
Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMNSHTMLTextAreaElement.selectionStart]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: javascript:alert(document.getElementById('ta').selectionStart); :: <TOP_LEVEL> :: line 1" data: no]
It seems like as soon as the textarea is invisible the selection can't be accessed.
