No, for some odd reason this has not yet been fixed and is still present in CC2019 unless you go to Sequence Settings > Settings and uncheck Composite in Linear Color.
There is however a free cross dissolve from Filminpact called Impact Dissolve that gives you more fine control that deals with this issue as well: https://www.filmimpact.net/blog/impact-dissolve-in-depth-video-tutorial (See the video)
Personally i do always uncheck Composite in Linear Color in my sequences only to avoid this issue.
