Missing attribute name value in cms-blo-detail.html.twig

### cms-blog-detail.html.twig:
##Line 3:

Missing attribute name "value"

 **...if element.config.fullWidth...**

should be changed to:

**...if element.config.fullWidth.value...**

Leads to error when blogDetail layout is re-saved. The blog posts are then shown in full width all the time. (SW 6.7.3.1)
