Describe the bug
When sorting by multiple rows/columns, e.g. first by property R1 and then by property R2, changing the sort order for R2 in the GUI breaks (resets) the sort order for R1. The original state cannot be restored (except by reloading the page).

To Reproduce
Steps to reproduce the behavior:

  1. Run the Playground snippet
  2. Expand Settings and both the rows to show the second level of the row hierarchy. Everything is fine here.

  1. Click on the "R2" sort icon. It changes R2 sorting to "descending" as expected, but also resets R1 sorting.

Expected behavior
R1 sort order should stay as is.
