At a lower level, I tried this, the underlying library for visnetwork functions:

library(visNetwork)
# minimal example
nodes <- data.frame(id = 1:3)
edges <- data.frame(from = c(1,2), to = c(1,3))
visNetwork(nodes, edges, width = "100%")

This also shows in the Plots pane but successfully displays.

See #2023; there's a known issue preventing some HTML widgets from showing up correctly in Positron. I think this is another instance of that problem.
