What could be causing my CSS to go unnoticed in my R Shiny application?

Explore the tooltip configuration I've implemented for the info icon in the code snippet below:

library(shiny)
ui <- fluidPage(
  span(
    `data-toggle` = "tooltip",
    `data-placement` = "auto",
    `data-trigger` = "click hover",
    title = "I'm a tooltip!",
    icon("info-circle", style="font-size: 150%;")),

  tags$script(
    HTML(
      "$(function () { 
        $('[data-toggle=tooltip]').tooltip();   
      });"
    )
  ),
  
  tags$style(
    ".tooltip.inner{background-color:red !important;}"
  )
)

server <- function(input, output) {}
shinyApp(ui = ui, server = server)

The default color of a tooltip's inner area is supposed to be black. However, I have specified CSS that should override this default and set the background color to red, but it persists as black. Why is this happening? Through inspection and research, I am confident that .tooltip.inner is the correct selector. It seems like my CSS rules are not being applied. I even attempted using an external CSS file instead of inline styling without success. This situation adds to a recurring issue where my App fails to recognize my CSS modifications, indicating a potential gap in my understanding...

Update: After receiving feedback from @piskunovim, I realized that I had misinterpreted your request for the inner feature. The code has now been adjusted to allow you to customize not only the tooltip button background but also the hover background and arrow color.

library(shiny)
ui <- fluidPage(
  span(
    `data-toggle` = "tooltip",
    `data-placement` = "auto",
    `data-trigger` = "click hover",
    title = "I'm a tooltip!",
    icon("info-circle", style="font-size: 150%; color: red;")),
  
  tags$script(
    HTML(
      "$(function () { 
        $('[data-toggle=tooltip]').tooltip();   
      });"
    )
  ),
  
  tags$style(
    ".tooltip-inner {background-color:red !important;}",
    ".tooltip-arrow {border-bottom-color: red !important;}"
  )
)

server <- function(input, output) {}
shinyApp(ui = ui, server = server)
