Height field in Banner Size settings forces 160px

Hi, when setting banner size, the height input field (e.g., next to "160 px") does not allow for percentage values (like "100%") or to be left blank for auto. It consistently saves a fixed pixel value, typically 160px. I confirmed that directly changing the s_size_height in the database to 100% works as expected. Please fix the form logic to allow auto or percentage heights.
Thank you.

Height with % is usually going to cause problems, because people do not know how to use percentage on height
So, use pixels instead.
