DT 0.26 crashes Javascript in PhantomJS via shinytest

[halhen]

DT 0.26 seems to crash Javascript execution in PhantomJS when using it with shinytest. The table is not rendered, and regular Shiny execution (e.g. updateSelectInput() etc) seems to stop.

Reproducible example:

File /tmp/test.R

library(shiny)
library(DT)

ui <- fluidPage(
  paste0("DT ", packageVersion("DT")),
  paste0("shinytest ", packageVersion("shinytest")),
  DT::dataTableOutput("table")
)

server <- function(input, output) {
  output$table <- DT::renderDataTable({
    data.frame(a = 1, b = 2)
  })
}

shinyApp(ui = ui, server = server)

# Install shinytest if missing
install.packages("shinytest")
shinytest::installDependencies()

# Run the test app and see a screenshot
a <- shinytest::ShinyDriver$new("/tmp/test.R")
a$takeScreenshot()

0.25

It's probably due to upgrading the DataTables library #1018, but debugging PhantomJS is far beyond my expertise...
