I had the following in a css file:
{
}
.. more stuff..
The editor does not allow a return after the }
If I add a section name:
abc{
}
I can add a line after the }
To test this take any css file, and type in two curly braces {}. You can add lines before and in the middle of the {}, but not after it. You can have as much text between the {} as you want. You can add text after the }.
