dplyr::bind_rows throws error 'error in vec_size' when binding tribbles

Question

Binding two tribbles

library(tidyverse)


dplyr::tribble(
  ~comp, ~val,
  "g", 100
) %>% 
  dplyr::bind_rows(
    dplyr::tribble(
      ~comp, ~val,
      "h", 100
    )
  )

results in the following error

Error in `vec_size()`:
! `x` must be a vector, not an environment.

This is not a result of masking:
