cacheDuration config not working with a string duration interval

[TraffordFewster]

We have had some complaints of our site caches not expiring, after digging into it a bit I found that us using a string duration interval is making the cache not have an end date.

Basic blitz.php config file

<?php

return [
    '*' => [
        // The amount of time after which the cache should expire (if not 0). See [[ConfigHelper::durationInSeconds()]] for a list of supported value types.
        'cacheDuration' => 'PT1S',
    ]
];

With the cache duration set to 'PT1S'which should be 1 second the cache never expires, if you change it to just a 1 the cache will expire. According to the ConfigHelper docs a string duration interval should be accepted but it doesn't appear to work.
