Plotly with custom aggregation and crosstalk

I am having trouble using plotly with custom aggregation and crosstalk. When using the crosstalk's filter, there seems to be some problem with the aggregation. When I set, for example, num1 filter to 0 - 0.87, the distribution starts to be uniform according to the plot which is not true. When using only one slider filter, the problem does not seem to be occurring. Moreover, as a rule of thumb, it seems to me that the more values I am to exclude, the more likely this issue is to happen. Here is a reprex

library(tidyverse)
library(plotly)
library(crosstalk)
library(htmltools)

dat <- tibble(
  cat = sample(letters, size = 12000, replace = T),
  num1 = runif(12000),
  num2 = runif(12000),
  count_helper = 1
)

dat_shared <- highlight_key(dat)


filters <- list(
  filter_slider("num1", "num1", dat_shared, ~num1, round = 2),
  filter_slider("num2", "num2", dat_shared, ~num2, round = 2)
)

p <- dat_shared |>
  plot_ly(
    x = ~cat,
    y = ~count_helper, 
    type = 'bar',
    transforms = list(
      list(
        type = 'aggregate',
        groups = ~cat,
        aggregations = list(
          list(
            target = 'y', func = 'count', enabled = T
          )
        )
      )
    )
  ) 

widget_out <- tagList(
  filters,
  p
)

Execute o R reprex fornecido com os dois controles crosstalk filter_slider e a transformação de agregação do plot_ly sobre cat e count_helper. Inspecione como a filtragem afeta a agregação; considera-se concluído quando as barras filtradas preservarem as contagens reais das categorias, em vez de se tornarem uniformemente distribuídas.
