ggplotly returns group_by_ error for ggplot with undefined dataframe

The following ggplot2 command fails when executed in ggplotly:

ggplot()+geom_line(aes(x = c(1,2,3,4), y = c(1,2,3,4), group = c(1,1,2,2))) #works

ggplotly(ggplot()+geom_line(aes(x = c(1,2,3,4), y = c(1,2,3,4), group = c(1,1,2,2)))) #fails

#>Error in UseMethod("group_by_") : 
#> no applicable method for 'group_by_' applied to an object of class "waiver"

This error can be addressed by assigning the data to a data frame and explicitly mapping the variables to the data frame within the ggplot call:

 df <- data.frame(x = c(1,2,3,4), y = c(1,2,3,4), group = c(1,1,2,2))

ggplotly(ggplot()+geom_line(data = df, aes(x = x, y = y, group = group))) #works 

ggplotly(ggplot()+geom_line(aes(x = df$x, y = df$y, group = df$group))) #fails

#>Error in UseMethod("group_by_") : 
#> no applicable method for 'group_by_' applied to an object of class "waiver"

先執行 issue 中的兩個 ggplotly 範例，並比較成功與失敗的情況。追蹤 ggplotly 對 inline aes 對應以及由 waiver 表示的 group 值的處理方式。完成的標準是兩個範例都能在沒有 group_by_ 錯誤的情況下進行渲染，同時保留分組線的行為。
