Arranging Stacked Bar Chart in R

I have been fiddling with a stacked bar chart, which I cannot get to sort from tallest to shortest. Here is the chart I have currently.

stacked bar chart

df7.csv

The code I am using is below:

ggplot(df7, aes(
  x = reorder(cause, failures) ,
  y = failures,
  fill = factor(
    part_number,
    levels = c(
      "UNKNOWN",
      "3766453",
      "20R7920",
      "3966006",
      "3976397",
      "20R7916",
      "20R7915"
    )
  )
)) +
  geom_bar(
    position = "stack",
    stat = "identity",
    width = 0.7,
    alpha = 0.75,
    color = 'black'
  ) +
  theme_minimal() +
  xlab('') +
  ylab('Failures') +
  labs(fill = "Part Number") +
  scale_fill_brewer(palette = "Dark2") +
  coord_flip()

Does anyone see why the chart is not sorting correctly? Thank you, and cheers!

reorder is a generic function for reordering factors. By default it reorders by mean. By default reorder uses a 'mean' function (FUN = mean by default) to reorder factors. By setting the FUN argument to sum reorder will sort the stacked columns by the sum total of the components to each bar.

The reorder section of the code should be replaced with the following:

reorder(cause, failures, FUN=sum)
