I just checked this bug in the latest stable release, 1.73.1, and it appears to have been fixed some time ago. I performed the following steps:

1. ctrl+n new file
2. Set language to plaintext
3. Pasted OP's example
4. Moved cursor to 1:1
5. Executed 'Fold'
6. Moved cursor to 6:1
7. Selected 6:1 to 6:3 ('abc')
8. Executed 'Select all occurences'
9. Typed A
10. Executed 'Unfold all' (this did nothing because everything was already unfolded)

It appears that 'Select all occurences' also performs an unfold which selects the folded in 'abc'.
