Description Alexander Pavlov (apavlov) 2012-05-29 06:06:26 PDT 
1. Set a screen resolution with the height of 900 or less.
2. Go to http://rezina.ua/ and scroll the page so that the SELECTs "Резина > Бренд" OR "Диски > Бренд" are exactly in the middle of the page
3. Click one of these SELECTs.

A popup with options is opened in the top of the page instead of immediately above or below the SELECT element. It can also overlap the SELECT element in certain circumstances.

Right.

Let's consider to introduce a unit test for the rect calculation later.
