I have the following tags:

• kde
• kubuntu
• kwin
• plasma
• plasma-5

Today I discovered that tagged questions have the following css:

.tagged-interesting {
    box-shadow: inset 0 1px 0 
    rgba(255,255,255,0.25);
}


.tagged-interesting {
    background-color: 
    #fffbec;
}

But the css seems to be applied only when two tags are present.

In the image above, questions 1, 2, and 4 have two of my tags and are highlighted. Questions 3 and 5 have only one of my tags and aren't highlighted.

I would expect the css to be applied even when one tag is present.
