ggplotly breaks custom, log transformed, axis labels

Unfortunately this does not show an error, only a warning. A better behavior would probably be returning an error when passing an expression.

See below for an example where the x axis has been log transformed.

plot_gg = ggplot(iris,aes(Sepal.Length,Sepal.Width,col=Species))+
    geom_point()+ 
    scale_x_continuous(trans = scales::log2_trans(),
                       breaks = scales::trans_breaks("log2", function(x) 2^x),
                       labels = scales::trans_format("log2", scales::math_format(2^.x)))
plot_gg

plot_ly=plotly::ggplotly(plot_gg)
plot_ly

Warning message:
In is.na(ticktext) :
  is.na() applied to non-(list or vector) of type 'expression'

首先运行 issue 中的 R 示例，并将 ggplot2 的输出与 ggplotly 的输出和警告进行比较。跟踪 ggplotly 如何处理经过变换的坐标轴刻度和表达式值标签；当该行为是有意设计的，并且由回归检查覆盖时即表示完成，可以通过正确处理这些标签，或清楚地报告不支持的表达式来实现。
