highlight heading title

[p00f]

How do i highlight heading titles?
setting it to

heading = {
  ["1"] = "+mygroup"
}

highlights only the contents under the heading like this

and setting it to

heading = {
  ["1"] = { title = "+mygroup"}
}

has no effect (I thought of doing this after grepping for TSAttribute)

I was frustrated by this for a while. For me what seemed to fix it was capitalising "heading" and "title", like this

Heading = {
	['1'] = { Title = '+mygroup' }
}
