Item sorting influences group sorting, but should not

[thinkh]

• Release number or git hash: 4.0.0-alpha.12
• Web browser version and OS: independent

Steps to reproduce

1. Open grouping.html
2. Remove all sorting and grouping from hierarchies
3. Sort number column in descending order
4. Group by cat2
5. Group by cat
6. Collapse second level grouping
7. Sort groups of cat in descending order
8. Open first group
9. Sort number column in ascending order
10. Toggle the item sorting a few times

Observed behavior

Sorting the items (after the sorting groups) orders all groups differently and seems to follow the item sorting. Toggling the item sorting a few times afterwards is only sorting the items within the groups (which is the expected behavior). However, the group sorting is never restored.

Expected behavior

Item sorting should not influence the group sorting and only sort items within the groups. Group sorting should only arrange whole groups.

@sgratzl I created a cypress test in branch https://github.com/lineupjs/lineupjs/tree/thinkh/291_item-sorting-influence. Not sure about the file naming convention and the selectors itself. Please feel free to revise it.
