Sorting multiple columns does not work (through columns editor)

[kspeeckaert]

Plugin version: 1.9.0
Grafana version: v11.3.0+security-01 (OSS Enterprise)

Given a table where 2 columns have the option Sort enabled, only the column that was last enabled will actually be sorted.

Screenshots:

Note: the screenshots illustrate the issue with grouping enabled, but it also occurs without grouping.

1.Only a single column sorted (level) → OK

2. Enabled sorting on another column as well (hostname) → NOK: table is sorted on hostname, but no longer on level (even though the option is still enabled).
   

3. Manually forcing sorting by shift-clicking the columns in the right order → OK
   

Thus:

• Multi-column sorting configured to the column editor does not work
• Multi-column sorting by shift-clicking the columns in the right order works, but is not retained
