input_code_editor(): caret is still off-set

[lgaborini]

Describe the problem

Same issue as #1303, the reprex is still valid:

library(shiny)
library(bslib)

ui <- page_fillable(
   layout_columns(
      card(
         card_header("Code Editor"),
         input_code_editor(
            "code",
            label = "Enter R code:",
            value = "f <- function(x) x + 1\nf(42)",
            language = "r",
            height = "200px"
         )
      ),
      card(
         card_header("Value"),
         verbatimTextOutput("value")
      ),
      col_widths = c(6, 6)
   )
)

server <- function(input, output, session) {
   output$value <- renderText(input$code)
}

shinyApp(ui, server)

There's no space at the end of the line but the caret moves there:
