Bug s3_dispatch() for cbind() #30

The generic should dispatch in cbind.default, why didn't it happen? The output in s3_dispatch() is correct, as I would expect. But that didn't happen when I use the generic. See the code below.

Code:
cbind.default <- function(x, ...) "Test!"
x <- 1:10
sloop::s3_dispatch(cbind(structure(x, class = "numeric")))
cbind(structure(x, class = "numeric"))

Example (Output):

cbind.default <- function(x, ...) "Test!"
x <- 1:10
sloop::s3_dispatch(cbind(structure(x, class = "numeric")))
cbind.numeric
=> cbind.default

• cbind (internal)

cbind(structure(x, class = "numeric"))
