Auto format don't remove multiple empty lines

If you create some empty lines (with or without indentions) between 2 {} brackets the auto format don't remove the empty lines.

The following example:

temp.foo = COA
temp.foo {
    
    
    
    
              
    
    
    
    
}

should be stripped to only one empty line between the brackets.

temp.foo = COA
temp.foo {

}
