Run the shinyjster test for the app https://github.com/rstudio/shinycoreci-apps/blob/master/apps/206-freeze-thaw/app.R The test fails on the last step.

    x: Fail

Could this be related to the recent tabset/tabset panel changes?

Note: Reviewing the runTests history, this is build this test started failing from https://github.com/rstudio/shinycoreci-apps/runs/2516442456?check_suite_focus=true

so around 7 days ago, from ~May 5th

Here's a minimal example

library(shiny)

ui <- fluidPage(
  uiOutput("tabs")
)

server <- function(input, output, session) {
  output$tabs <- renderUI({
    tabsetPanel(
      tabPanel("A", "a"),
      tabPanel("B", "b")
    )
  })
}

shinyApp(ui, server)

The .active tab styling doesn't show up because this renderHook never gets called because renderUI() runs through shiny:::processDeps() which uses doRenderTags() (not renderTags())
