Facet labels get cut off when rotated

I suspect this is a similar issue to #1224 : when graphs are facetted vertically, and the facet labels rotated to be horizontal, the labels are cut off. (Where there is a legend, it overlaps; where there isn't, it's cut off entirely.)

p <- flights %>%
  ggplot(aes(y=origin, x=dest, colour=origin)) +
  geom_count() +
  facet_grid(name ~.) +
  theme(strip.text.y = element_text(angle = 0),
        legend.position = "none")
ggplotly(p)

首先运行 issue 中的 R 复现，并将行为与 issue #1224 进行比较。跟踪 ggplotly 使用的 facet 标签渲染路径，然后验证水平旋转的标签是否完整可见且不会与图例重叠，同时检查有图例和无图例两种情况。
