Extra column disappears when changing filter

[datamuc]

Describe the bug
When viewing services in detail style and adding an extra column, that column is removed whenever the service filter is changed.

Thruk version
version used on demo.thruk.org (demo instance)

To reproduce

1. Open: https://demo.thruk.org/demo/thruk/cgi-bin/status.cgi?style=detail&dfl_s0_type=service&dfl_s0_val_pre=&dfl_s0_op=%7E&dfl_s0_value=ssh
2. Add an extra column (e.g., "Execution time") to the table.
3. Change the service filter value
4. Observe that the extra column disappears.

Expected behavior
The extra column should remain visible when the filter is changed; only the row set should change.
