Description

As shown in screenshot the styling of the backend is broken in IE9 and not usable.
I tried every Browser and Document mode, none was working. I tested with three different versions.
A blank installation, one with bootstrap package and a all setup Webseite (all 7.6.12) - same behavior of broken backend.

The problem is that IE9 has a CSS limitation of 4096 selectors in each CSS file
The backend.css of typo3_src-7.6.12/typo3/sysext/t3skin/Resources/Public/Css/backend.css consists of 4556 selectors

After splitting the file in 2 css files the backend works lika a charme in IE9. Worked as a hotfix for me.
But better solutions should be provided.
