Duplicate test for unmatched brackets in query parameters.

The test cases at lines 4511-4513 and 4797-4799 are duplicates, testing the same functionality of checking for unmatched brackets in query parameters. Consider consolidating these tests or ensuring they cover different scenarios to avoid redundancy in the test suite.

Also applies to: 4797-4799
