Vayne and the Terrain changes

With the most recent changes to Jarvin's and Anivias wall that they are treated like part of the map only temporary. I'm not sure if this is intended, but vayne cant tumble through anivias wall nor any other terrain in the game, however she can still tumble out of Jarvin's ultimate. Is this intended? If not I'm reporting it. If it is, I feel like it should be changed. It makes sense that champs that have dashes can still get out, because they can go over other terrain in maps.
