formatDate() returns 'medium' when called 'short' in Magento 1.9.2.3

Question

I recently did an upgrade from Magento 1.8.0.0 to 1.9.2.3. Since then the Core Helper Function formatDate() returns the 'medium'-formatted date, even if called with 'short'.

Example (output from magerun dev:console):

Magento 1.8.0.0:

>>> Mage::helper('core')->formatDate('2011-06-28 08:50:51', 'short')
=> "28.06.11"
>>> Mage::helper('core')->formatDate('2011-06-28 08:50:51', 'medium')
=> "28.06.2011"

Magento 1.9.2.3:

>>> Mage::helper('core')->formatDate('2011-06-28 08:50:51', 'short')
=> "28.06.2011"
>>> Mage::helper('core')->formatDate('2011-06-28 08:50:51', 'medium')
=> "28.06.2011"

As far as I can see the formatDate() itself didn't change. Also my system configuration didn't change. Is it a bug? Can anybody reproduce? Thanks.

Since Magento CE 1.8.1.0, Mage_Core_Model_Locale::getDateFormat() always returns a four digit year part, no matter which date format is passed in.

To create the desired output format, you need to bypass the Mage_Core_Helper_Data::formatDate() method.
