layout breaks with facet_wrap when employing scales=free

I have a problem combining plotly::ggplotly (v4.7.1) with facet_wrap (v3.0.0) that I can't seem to generalise but is reproducible with a particular dataset (summary metrics for a set of tweets):

require(tidyverse)
require(plotly)
d = read_csv('https://gist.githubusercontent.com/geotheory/21c4eacbf38ed397f7cf984f8d92e931/raw/9148df79326f53a66a8cc363241a440752487357/data.csv')
d = d %>% mutate(key = fct_reorder(key, n)) # order the bars
p = ggplot(d, aes(key, n)) + geom_bar(stat='identity') + 
  facet_wrap(~ set, scales='free', nrow=1) +
  labs(x=NULL, y=NULL) + coord_flip()
print(p)

Enter ggplotly:

print(ggplotly(p))

This seems to relate to the combination of nrow=1 and scales='free' arguments. Any ideas about the cause?

Comece executando o exemplo de R fornecido com o conjunto de dados vinculado e as versões informadas de ggplot2 e plotly, comparando as renderizações de ggplot e ggplotly. Rastreie como ggplotly lida com facet_wrap com scales='free', coord_flip() e nrow=1. Considera-se concluído quando o gráfico convertido preserva o layout esperado dos facets sem quebrar as escalas livres.
