Webshot cuts off images with plotly widgets

[kmalone7]

I am trying to include static images of plotly widgets in my rmarkdown reports. I like the interactively of plotly so I save the widgets locally, but they take up too much space when knitting. I have been able to do this by two ways. Either in the code chunk using the option screenshot.force=TRUE (uses webshot) or saving the widget locally with saveWidget() and then using the webshot() function. The issue is that the image is cut off at the lower portion of the y-axis, which is bothersome. I would expect the whole image to be saved with webshot. I have tried adjusting the features of vwidth, vheight, and cliprect with no luck. Though this seems to work properly with other widgets like leaflet.

To reproduce make any simple plot_ly plot, save the widget with saveWidget, then save a png with webshot.

Example script:
require(webshot)
require(plotly)
require(htmlwidgets)
data("iris")
simple_plot=plot_ly(x=iris$Petal.Width,y=iris$Petal.Length,type="scatter",mode="markers")
saveWidget(widget = simple_plot,file = "simple_plot.html")
webshot(url = "simple_plot.html",file = "webshot_iris.png")

To see this I am attaching image from webshot (second image) and a manual screenshot from savewidget (first image). Notice that the webshot version is cut off with the lower numbers on the y-axis

I have same issue! (with same version of packages plotly_4.8.0 webshot_0.5.1)
It was working previously for me.
However I decided to upgrade all my packages and now I face same issue.
Given I upgraded all packages at once I am unable to tell if the issue started with a new version of webshot or of plotly

Similar reproducible example as above

library(plotly)
library(webshot)

# install_phantomjs() # this has installed https://github.com/wch/webshot/releases/download/v0.3.1/phantomjs-2.1.1-windows.zip

data <- data.frame(x=1:100, random_y=rnorm(100, mean = 0))
widget <- plot_ly(data, x = ~x, y = ~random_y, type = 'scatter', mode = 'lines')

tempfile = tempfile(pattern = "widgetToPng_")
filePathHTML = paste0(tempfile,".html")
filePathPNG  = paste0(tempfile,".png")

htmlwidgets::saveWidget(widget = widget, file = filePathHTML) # at this stage the html is complete

webshot(url = filePathHTML, file = filePathPNG)

It appears https://github.com/rstudio/webshot2 doesn't suffer from this issue...consider using webshot2::webshot() instead.
