rhbz#1589029 tdf#93789 impress not showing text highlight in presentation mode

the text hightlighting feature was implemented backed on to the vcl
TextFillColor feature. TextFillColor fills the background of the bounds
of the text with that color

Likely either the same problem or similar as tdf#93789
