Scrolling on preview pane not working with inner scrollings areas

[dimti]

Hi

Today i find this problem: If on a page exists inner scroll area blocks, then tab scope scrolling on preview pane - not working for this inner scrolling area

How to repeat: Try to use web-application with inner scrolling areas and try to scroll that areas on preview pane (I use roundcube, and i unable scroll email-message content area on a message page)

Same problem may be viewed on gmail web-interface
