legendrank (bar chart example)

This bug report concerns R plotly 4.10.1.
I was going to file a report regarding a more complex composite chart; involving bars and lines; as I noticed when there was an NA(or NaN) value to plot against the Y axis , the legend orders got scrambled. I was able to directly address this shortcoming in my own code by na.omit() on my input dataset. However , in the course of trying to simplify my code down to be more minimal for this reprex, I encountered a more basic issue of the legendrank seemingly not being respected

library(plotly)

  rank = structure(c(
    1L, 1L, 1L, 1L, 2L, 2L, 2L,
    2L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 4L
  ), levels = c(
    "1", "2", "3",
    "4"
  ), class = "factor"), value = c(

# table(tot_df$series_name_text,tot_df$my_legend_rank
#                  1 2 3 4

plotly_json(px)

It seems to me that based on legendrank 'Reference stat1 should be the first i.e. leftmost trace name observed within the legend box, and this isnt the case, the first seen is Current stat1, that should be in 3rd position...)
Is there a gotcha here ? some incorrect setup ? something that invalidates the use of legendrank ?

Run the supplied R reprex and inspect plotly_json(px), focusing on how the legendrank mapping is represented for the bar traces. Compare the generated legend order with the requested ranks; done means either the traces appear in rank order or the issue is explained and covered by an appropriate regression test.
