Additional context

This began to happen after the last three commits. This one works: f0077c3726d243eeaabd2ec280216e8c3ca7da9f

While submitting this issue, I discovered that if I rewrite my config, everything works, but I decided to create an issue anyway so that others could find it.

setup({
  surrounds = {
   ["("] = {add = {"(", ")"}},
    c = {add = {"#_", ""}},
  }
})
