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.

Inizia eseguendo l'esempio R fornito con plotly::subplot() e confronta i pannelli sunburst e treemap con i pannelli scatter. Esamina il comportamento del dimensionamento di subplot e l'avviso 'layout' riportato; il lavoro è completato quando i grafici sunburst e treemap vengono ridimensionati correttamente senza quell'avviso.
