When the sections are collapsed and a "select all" operation is performed to copy the data somewhere else, the data content of the last style is not included in clipboard.
Steps to reproduce:
1- Create a new CSS file and add something. Ex:
.test {
background-color: black;
}
2- Collapse the view
3- Edit -> Select All
4- Edit -> Copy
5- Start Notepad and paste the data
