Column named "count" silently used when running in proportions mode

Running sccomp with cell type proportions silently uses a column named "count" from the input data.

The following code constructs a model using cell type proportion values. The column "count" is included incidentally and is not supplied to the function. This code runs correctly.

library(dplyr)
library(tidyr)
library(sccomp)
data("seurat_obj")
data("sce_obj")
data("counts_obj")

counts_obj = 
  counts_obj |>
  mutate(count = count+1) |> 
  with_groups(sample, ~ .x |> mutate(proportion = count/sum(count)))

set.seed(1)
counts_obj_results_with_count <- 
    counts_obj |>
    sccomp_estimate(
        formula_composition = ~ type , 
        .sample = sample,  
        .cell_group = cell_group, 
        .count = proportion
    )

counts_obj_results_without_count |>
    sccomp_test() |>
    sccomp_boxplot(factor = "type")

When "count" is removed, sccomp_estimate runs but some downstream analysis functions do not.

counts_obj <-
    counts_obj |>
    select(- count)

set.seed(1)
counts_obj_results_without_count <- 
    counts_obj |>
    sccomp_estimate(
        formula_composition = ~ type , 
        .sample = sample,  
        .cell_group = cell_group, 
        .count = proportion
    )

counts_obj_results_without_count |>
    sccomp_test() |>
    sccomp_boxplot(factor = "type")

Here, sccomp_boxplot produces the error:

Error in `select()`:
! Can't select columns that don't exist.
✖ Column `count` doesn't exist.

The "count" column also appears to be used for some calculations. In boxplots, the blue outline is flattened if count is set to all equal 0.
