Setting driver option for mysql in the UI results in a wrong entry in local.php

setting “buffer_result” = “true” for mysqli over the UI generates the entry:

‘driver_options’ => [
‘buffer_results’ => ‘true’,
]

in the file config/autoload/local.php AND HAS NOT THE EXPECTED RESULT correct would be:

‘options’ => [
‘buffer_results’ => ‘true’,
]

this manually corrected entry produce the expected result - ist however not show in the UI
