When a widget's flow preference is set to RTL, we adjust the render transform so that the horizontal transform is mirrored (see SWidget::GetRenderTransformWithRespectToFlowDirection). We should do the same with the shear setting as well. Shear is folded into the render transform via ToSlateRenderTransform at the UWidget level, so the SWidget will have to do some additional work to separate out the different transformations that are applied and mirror the shear horizontally.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-172713 in the post.
