`color_tiles()` ignores `colDef`s `na=` argument

[eastclintw00d]

I wanted to use color_tiles and came across the issue that it ignores the na= argument from colDef and prints out the missing values as NA.

library(reactable)
library(reactablefmtr)
library(dplyr)

tile_column <- function(x) {
  colDef(
    show = TRUE, 
    na = "",
    cell = color_tiles(
      x,
      colors = c("red", "orange", "yellow", "limegreen", "green"),
      number_fmt = scales::percent_format(scale = 1, accuracy = .1, decimal.mark = ",", big.mark = "."),
      box_shadow = TRUE,
    )
  )
}

data <- tibble(
  col1 = c(1, 4, 2, 5, NA_integer_, 2),
  col2 = c(2, 1, 2, NA_real_, NA_real_, 2),
)

data |> reactable() ## works -> no NAs are printed

data %>%
  reactable(
    columns = list(
      col1 = tile_column(.),
      col2 = tile_column(.)
    )
  ) ## does not work

Can you please have a look and maybe fix this?

Note that in my real application I still want to be able to color a tile by another column although its label is NA. The tile should not vanish entirely.
