Photoshop Animation with Transform: Can i Animate *MASK-Transformation* continuously?

Question

Hello, i edit software video tutorials on the Photoshop timeline*. Sometimes i want to zoom into a screen area and show the action there enlarged.
Let's say my tutorial explains Photoshop's layer techniques. The screen cast shows the whole Photoshop workspace including the layer panel. Now in the tutorial, i want to zoom into the layer panel with 200 %, so that viewers see the mouse action and thumbnails there better, while still a good part of the workspace including the image is visible (so you get the enlarged layer panel and see how it affects the image). To zoom smoothly into the layer panel area,
i make a smart object of the footage,
duplicate it into a new video group,
create a vector mask around the layer panel (my area of interest),
start the Transform stop watch on the time line
move the timeline cursor half a second further and
transform the layer to 200 % (using pixel replication)
In the result, the screencast itself is nicely zoomed into. But the mask is never zoomed – it is either one size or the other, and there's no difference whether using vector masks or layer masks (i prefer vector masks of course).
I see that there are more stop watches for
- vector mask position
- vector mask active
But they don't help and i don't fully understand them. I read a lot and saw some tutorials, but still don't understand the situation.
Is it possible or not that the mask is contuinuously scaled larger and smaller together with the footage itself?
By the way, i know how to show an enlarged screen area without the zooming-in. I can simply fade in. That works nicely. But i would love to show the zooming-in.
Or should i do that kind of work in another application altogether?
Thanks for any clues (or links) you might give me!
*aware that there are other solutions, but usually works well for me

You did not look down far enough. Below them are some layers in blue (or other solid color) Twirl down the one that says 3D Meshes. Click on the small stopwatch for the object move your playhead ahead in time then rotate your mesh. The easiest way to rotate the mesh is using the text fields in the mesh's properties.
