sunburst and treemap plots aren't resized when displayed in subplot

Using plotly 4.9.2.9000 (latest GitHub) sunburst and treemap plots aren't resized when displayed in a subplot.

Furthermore a warning is given:

Warning message:
'layout' objects don't have these attributes: 'NA'

Example:

library(plotly)

p1 <- plot_ly(
  labels = c("Eve", "Cain", "Seth", "Enos", "Noam", "Abel", "Awan", "Enoch", "Azura"),
  parents = c("", "Eve", "Eve", "Seth", "Seth", "Eve", "Eve", "Awan", "Eve"),
  values = c(10, 14, 12, 10, 2, 6, 6, 4, 4),
  type = 'sunburst'
)

p2 <- plot_ly(
  labels = c("Eve", "Cain", "Seth", "Enos", "Noam", "Abel", "Awan", "Enoch", "Azura"),
  parents = c("", "Eve", "Eve", "Seth", "Seth", "Eve", "Eve", "Awan", "Eve"),
  values = c(10, 14, 12, 10, 2, 6, 6, 4, 4),
  type = 'treemap'
)

p4 <- p3 <- plot_ly(y = 1:10, type = "scatter", mode = "lines")

plotly::subplot(p1, p2, p3, p4)

First saw this issue here.

首先使用 plotly::subplot() 运行提供的 R 示例，并将 sunburst 和 treemap 面板与 scatter 面板进行比较。调查 subplot 的尺寸行为以及报告的 'layout' 警告；当 sunburst 和 treemap 图能够正确调整大小且不再出现该警告时，即表示完成。
