The divider prop was only being set when title was present, and the
default value for divider is true. This unconditionally sets the divider
prop.

Some homepage cards would like to define their own header
for example, so that a title can be set dynamically.
Removing the divider with the divider prop provides a way to put
everything in the content area without an extraneous divider above.
The divider is usually not easily visible using the default theme,
however customized themes that may use a larger border-radius this
divider becomes visible and distracting.
