req_perform_parallel() string parameter not working since version 1.1.1

[Eli-Berkow]

With version 1.1.0 and prior, the following example works with a string for the progress parameter:

library(shiny)
library(httr2)

ui <- fluidPage(
    htmlOutput('resps')
)

server <- function(input, output, session) {
    output$resps <- renderUI({
        request_base <- request(example_url())
        reqs <- list(
            request_base |> req_url_path("/delay/1"),
            request_base |> req_url_path("/delay/1")
        )
        parallel_progress=req_perform_parallel(reqs, progress = 'Running')
        HTML('done')
        })
}

shinyApp(ui, server)

Replacing the string 'Running' with TRUE gives the below default:

From version 1.1.1 there is no progress bar at all for strings and the following shows for the default TRUE option:

Has there been a change in the way that parameter is used?
Thanks in advance
