Include content element container setting in class attribute

[vmans]

Why is the content element setting "container" - that is, ['data']['tx_t3sbootstrap_container'] - not included in the classAttr so that it has effect in the frontend according to the Bootstrap styling? That's so for a long time, so there must be a reason. Does it interfere with general settings? Otherwise:

BootstrapProcessor.php starting at around line 392, make something roughly like this:

        $processedData['class'] = !empty($processedData['trimClass']) ? ' '.$processedData['container']' '.$processedData['trimClass'] : '';
        $processedData['classAttr'] = !empty($processedData['trimClass']) ? ' class="'.trim($processedData['class']).'"' : '';
