Hello,

Test case: https://live.datatables.net/gigegefu/2/
Steps to reproduce:

Initial state

Order: "Name", "Position", "Office", "Age", "Start date", "Salary"
→ Save as "State 1"

Swap two columns

Move "Position" and "Office" to get: "Name", "Office", "Position", "Age", "Start date", "Salary"
→ Save as "State 2"

Hide a column

Hide "Office" to get: "Name", "Position", "Age", "Start date", "Salary"
→ Save as "State 3"

Test state restoration

Load "State 1" → ✓ OK: "Name", "Position", "Office", "Age", "Start date", "Salary"
Load "State 3" → ❌ ISSUE: "Name", "Office", "Age", "Start date", "Salary"
Load "State 2" → ✓ OK: "Name", "Office", "Position", "Age", "Start date", "Salary"
Load "State 3" → ✓ OK: "Name", "Position", "Age", "Start date", "Salary"

Expected result: When first loading "State 3", the order should be "Name", "Position", "Age", "Start date", "Salary"
Actual result: The "Office" column appears in place of "Position"
