It seems like it’s the same issue, the menu does not calculate the content height correctly.
I’ve quickly put together a script which might help you. But please note that this qualifies as a customization request, and I cannot guarantee that it will work in all cases correctly. Try adding this custom code to the functions.php file in your theme directory (copy from line 3):
IMPORTANT: Please have a full site back-up before proceeding to edit your theme file, as well as use an FTP connection to make the changes.
Also, I highly suggest looking at the menu script to fix the height calculation issue, as these solutions may not work permanently, or in all cases.
I hope this helps!
