Time series plot x range starts from 1970

When I'm trying to plot a time series coloured by the value of variable, the date range starts from 1970. It defaults to a sensible date if I exclude the color argument. I can certainly manually specify the xaxis range, but when I double click the plot to reset the scale it goes back to the 1970 range again, which is quite annoying.

library(lubridate)
library(plotly)

data <- data.frame(date = seq(from = ymd_hms("20190101 000000"), 
                              to = ymd_hms("20190301 000000"), 
                              by = "1 hour"),
                   y = round(runif(1417, 0, 10)))

data %>%
  plot_ly(x = ~date, y = ~y, color = ~y) %>%
  add_markers()

从使用 plot_ly(x = ~date, y = ~y, color = ~y) 和 add_markers() 的可复现 R 示例开始，并将其与省略 color 的情况进行比较。调查 x 轴重置为何使用 1970 年的范围，并验证双击重置是否能在不手动指定 xaxis 范围的情况下保留 2019 年的日期范围。
