Prevent copy paste of email confirmation in Confirm Email Address Entry plugin

[AlexThibo]

No luck... I added this:

 onCopy="return false" onDrag="return false" onDrop="return false" onPaste="return false" autocomplete="off"

In both the email and the email-confirmation text boxes of both files: tpl_account_edit_default.php and tpl_modules_create_account.php. So the code looks like that:

<label class="inputLabel" for="email-address" onCopy="return false" onDrag="return false" onDrop="return false" onPaste="return false" autocomplete="off"><?php echo ENTRY_EMAIL_ADDRESS; ?></label>

<?php echo zen_draw_input_field('email_address', $account->fields['customers_email_address'], 'id="email-address"') . (zen_not_null(ENTRY_EMAIL_ADDRESS_TEXT) ? '<span class="alert">' . ENTRY_EMAIL_ADDRESS_TEXT . '</span>': ''); ?>

<br class="clearBoth" />

<label class="inputLabel" for="email-address-confirm" onCopy="return false" onDrag="return false" onDrop="return false" onPaste="return false" autocomplete="off"><?php echo ENTRY_EMAIL_ADDRESS_CONFIRM; ?></label>

<?php echo zen_draw_input_field('email_address_confirm', $account->fields['customers_email_address'], 'id="email-address-confirm"') . (zen_not_null(ENTRY_EMAIL_ADDRESS_CONFIRM) ? '<span class="alert">' . ENTRY_EMAIL_ADDRESS_TEXT . '</span>': ''); ?>

<br class="clearBoth" />

Again, absolutely no difference on the possibility to copy/paste. That should work but it doesn't. How is this possible?
