Aspect ratio with small multiples / subplots

I would like to create small multiples with a fixed aspect ratio. However, there seems to be a but somewhere and only some plots retain the correct aspect ratio.
From what I gathered, setting a fixed aspect ratio with plotly is done as follows: layout(yaxis = list(scaleanchor = "x"))

Consider the follwing example:

df <- data_frame(
  x = rep(1:5,25),
  y = rep(1:5,25),
  g = sort(rep(1:25,5))
)

plots <- df %>%
  split(.$g) %>%
  map(function(x){
    plot_ly(data = x, x = ~x, y = ~y, type = "scatter",mode = "lines") %>% add_lines()
  })

small_mulitples <- subplot(plots,nrows = 5) %>%
  layout(yaxis = list(scaleanchor  = "x")) %>%
  hide_legend()

If I plot small_mulitples, only the first plot (row 1, column 1) has an aspect ratio of 1. The other have an arbitrary aspect ratio.

Here's the link to the interactive version of this plot: https://plot.ly/~rata_zhaw/1/

Interestingly, if I choose the option shareX = T in subplot(), the entire first column has the correct aspect ratio. Nothing changes if I choose shareY = T

small_mulitples <- subplot(plots,nrows = 5, shareX = T) %>%
  layout(yaxis = list(scaleanchor  = "x")) %>%
  hide_legend()

And here's the link to the interactive version of the second plot: https://plot.ly/~rata_zhaw/3/

If I plot any of the plots individually, the aspect ratio is correct:

plots[[10]] %>%
  layout(yaxis = list(scaleanchor  = "x")) %>%
  hide_legend()

首先，使用 subplot()、nrows = 5 和 layout(yaxis = list(scaleanchor = "x")) 重现所提供的 R 示例；将其与 shareX = T 和单图的情况进行比较。跟踪 subplot() 如何组合各个图的布局，并在每个 small multiple 都能保持固定纵横比而无需共享坐标轴时，认为该 issue 已完成。
