Transmission no longer displays portrait

[FaceJaraxxus]

Hi! I just now discovered an issue that must've been introduced recently.

Unit transmissions with the removed UI style borders no longer display portrait.

        call TransmissionFromUnitWithNameBJ(GetPlayersAll(), whichUnit, GetHeroProperName(whichUnit), null, transmissionString, bj_TIMETYPE_SET, 7.00, true)

Previously it used to show portrait, unit name and message string on a transparent black blackground. Is the issue known? Is there a work-around, or do I just have to change mode if I want the portrait?

Thanks!
