Animated bubble plot - bubble not resizing when selection made via highlight

When creating an animated bubble plot the bubbles in the selection set (made through highlight - plotly_click) do not resize.
Example below is based on example from here https://plotly-r.com/client-side-linking.html

library(plotly)
library(ggplot2)
library(gapminder) 

#modify some pop values to make bubbles stand out more
gapminder$pop = ifelse(gapminder$year > 1982 & gapminder$country =='China', gapminder$pop * 10, gapminder$pop)


g <- highlight_key(gapminder, ~continent)

gg <- ggplot(g, aes(gdpPercap, lifeExp, 
      color = continent, frame = year)) +
      geom_point(aes(size = pop, ids = country)) +
      scale_x_log10()

p_gg <- highlight(ggplotly(gg), "plotly_click")

p_gg

Selecting by clicking on the bubble Not resizing

Expected results

Using Plotly box selection As expected

With no selection

可复现示例使用了 highlight_key()、ggplot()、ggplotly() 和 highlight(..., "plotly_click")；首先运行该示例，并比较点击选择与框选。完成的标准是：选中的气泡在动画图中能够一致地调整大小，同时未选中视图和现有的框选行为保持不变。
