TYPO3 Core

Adding .spacing to a Gifbuilder text object breaks the linebreaking. If I remove the "10.spacing = 1" line from the code below, the text breaks nicely but as soon as it is added, no line breaking happens anymore. The same happens without .breakWidth and .breakSpace when the linebreak is added in the header text itself.
It seems the code used for adding the spacing between letters doesn't include any page breaking logic.

TypoScript example:

temp.header1 = IMAGE
temp.header1.file = GIFBUILDER
temp.header1.file {
XY = [10.w]+3,[10.h]+10
backColor = #ffffff
transparentBackground = 1

10 = TEXT
  10.text.data = field:header
  10.fontColor = #000000
  10.fontSize = 33
  10.fontFile = fileadmin/template/American.ttf
  10.spacing = 1
  10.breakWidth = 360
  10.breakSpace = 1.2
  10.offset = 0,25
  10.niceText = 0
  10.antiAlias = 1
}
