Sometimes, when moving strip with 2 input effect attached and causing strip overlap, this overlap is resolved incorrectly - too big offset is applied. This is because effects are not taken into consideration when "shuffeling" to resolve overlap. To fix usual cases (transitions), overlap between strip and it's effect is considered to be impossible. There are edge cases, but these would be much more complicated to implement and could have negative impact on performance. Reviewed By: ISS Differential Revision: https://developer.blender.org/D14578
