Title: Build [377.g5ec88c79ddf9] Layer Hierarchy seems to be slightly broken, i have noticed this with matte clips and x-spline layers.

It seems the top most layers are not being omitted/ignored properly. Specifically if you have a wall or object that begins to occlude the object you are tracking. This happens with both Matte clips and rotos with x-splines.
The track will drift as soon as the occlusion happens or an error will pop up stating “Tracking terminated prematurely” and then " one or more layers were not tracked properly. Try increasing the minimum percentage of pixels used."
It seems when using an x-spline for tracking, that Mocha is occluding the entire plate when you place a fg spline over the occlusion, disregarding the shape or size of the x-spline. if you swap the layer order and place the layer to the very top it will track just fine until the occlusion intersects your track.
Steps to reproduce:
Run some tests on layer hierarchy to recreate this issue specifically with an object passing behind a wall, car or similar. We have noticed this happens almost every single time, with matte clips or x-splines.
Expected result: Tracking objects that become occluded by foreground objects without drift or track disruption.
Actual Result: x-spline drifts or tracks foreground objects that are occluded by masks or matte clips.
Regression: It was not in an older build but i don’t remember which it was working in specifically.
Additional data: i will try to provide screen grabs of some sort but this is difficult do to the nature of the work.
