zoomie | JavaScript zoom-on-hover tool | Plugin library

I'm trying to make an animation that transitions as you scroll. I need it to reverse while scrolling up. I know this is possible (here's an example) but I can't get a similar behavior to work in React.

I made this demo as a way to simplify my issue (based on what's in AnimeJs's docs):

At the moment I'm working on a project with point pattern events on a linear network (car crashes) and I'm reading chapter 17 of spatstat book: "Spatial Point Patterns: Methodology and Applications with R".

The authors of the book explain that they defined a new class of objects called lpp for analyzing point patterns on a linear network. The skeleton of each lpp object is a linnet object and there are several functions to create a linnet object. For my application the relevant functions are linnet and as.linnet. The function linnet creates a linear network object from the spatial location of each vertex and information about which vertices are joined by an edge, while the as.linnet function can be applied to a psp object which is transformed into linnet objects inferring the connectivity of the network using a specified distance threshold.

The reason why I'm asking this question is that I don't know how to efficiently create a linnet object starting from a sf object with a LINESTRING geometry. As far as I know, it's possible to transform the sf object into an sp object (i.e. a SpatialLines object), then I can transform the sp object into a psp object (using as.psp function) and then I can transform the psp object into a linnet object using the as.psp.linnet function (which is defined in the maptools package). The main problem with this approach (as the authors of the package said in their book) is that the inferred network is wrong every time an overpass or an underpass occurs in my network data since the corresponding linnet will create artificial intersections in the nework. Moreover, as the authors said in their book, the code gets exponentially slower.

The following code is a simplified version of what I did so far but I think that there must be an easier and better way to create a linnet object from an sf object. I would use the linnet function but the problem is that I don't know how to create a (sparse) adjacency matrix for the corresponding vertices of the network or a matrix of links between the edges of the network.

I got a 4x4 grid of videos, and I have created an onclick to zoom in on a video. But when I used the animation to change the position of the clicked video, the rest of the grid changes structure.

How can I tell the other videos to stay in place, or add a placeholder div maybe? The holder div is an attempt to have a placeholder.
