CSV export does not escape strings when needee

[René]

Describe the bug
When using the option to export a table as CSV file, fields containing the separator value are not properly exported and result in extra columns when opening in spreadsheet software.

To Reproduce
Steps to reproduce the behavior:

1. Create table with data:

CREATE TABLE `test` (
  `string` varchar(255) NOT NULL,
  `another_string` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci;

INSERT INTO `test` (`string`, `another_string`) VALUES
	("Mozilla/5.0 (Linux; Android 14; SAMSUNG SM-A528B) AppleWebKit/537.36 (KHTML", "Some"),
	("One,Not two", "Two");

3. Now export the table to CSV
4. See result:

string;another_string
Mozilla/5.0 (Linux; Android 14; SAMSUNG SM-A528B) AppleWebKit/537.36 (KHTML;Some
One,Not two;Two
