That's because you add a property which was unspecified by the
original face.  But in the tooltip case, the function tooltip-show
propertizes the entire text it receives with the 'tooltip' face, so
any face attributes in the text that are also specified by the
'tooltip' face will be overwritten.  So, for example, if the tooltip
text had a :background attribute, that attribute would be overwritten
by the background color of the 'tooltip' face.  Isn't that what you
see?
