Steps to reproduce:

1.) Open the attached file “bug.mss” in Kate.
2.) Click on code folding at line 1: The lines 2, 3, 4 are hidden as expected. The last line (line 5) with the closing “}” isn’t hidden.
3.) Click again on code folding at line 1: The lines 2, 3, 4 appear.
4.) Click on code folding at line 2: The lines 3, 4 are hidden. This time, the line with the closing “}” (line 4) is hidden.
5.) Now, lines 1, 2, 5 are visible. Click on code folding at line 1: Nothing happens.

Bugs:

A:
Current behaviour: The behaviour of step 2 and step 4 isn’t consistent: One time, the line with the closing “}” is hidden, another time not.
Expected behaviour: The behaviour is consistent in both situations.

B:
Current behaviour: In step 5, nothing happens.
Expected behaviour: Code folding as usual.
