Consistent height of widgets

Even though I didn't specify any theme, the default theme is pretty good looking already, but I noticed that all the widgets seem to be a bit taller, which takes up some space, that's fine, they still align.
But when I used the extension Buttons in DT, I noticed the problem, it doesn't have the same height as the search box and the pagination control in DT, unify it in the future, or will I have to add a custom theme?
Here is an example to explain the misalignment I see, compared to shiny without bslib.

library(shiny)
library(DT)

shinyApp(
  ui <- fluidPage(
    fluidRow(
      column(6, DTOutput("table_1")),
      column(6, DTOutput("table_2")),
    )
  ),
  server <- function(input, output, session) {
    df <- data.frame(a = 1:3, b = 4:6, c = 7:9)
    output$table_1 <- renderDT({
      datatable(
        df,
        extensions = 'Buttons',
        options = list(
          dom = "Brftip",
          buttons = list(
            "csv", "copy"
          )
        )
      )
    })
    output$table_2 <- renderDT({
      datatable(
        df,
        extensions = 'Buttons',
        options = list(
          dom = "Bprt",
          buttons = list(
            "csv", "copy"
          )
        )
      )
    })
  }
)

library(shiny)
library(DT)
library(bslib)

shinyApp(
  ui <- page_fluid(
    fluidRow(
      column(6, DTOutput("table_1")),
      column(6, DTOutput("table_2")),
    )
  ),
  server <- function(input, output, session) {
    df <- data.frame(a = 1:3, b = 4:6, c = 7:9)
    output$table_1 <- renderDT({
      datatable(
        df,
        extensions = 'Buttons',
        options = list(
          dom = "Brftip",
          buttons = list(
            "csv", "copy"
          )
        )
      )
    })
    output$table_2 <- renderDT({
      datatable(
        df,
        extensions = 'Buttons',
        options = list(
          dom = "Bprt",
          buttons = list(
            "csv", "copy"
          )
        )
      )
    })
  }
)

Start by running the two minimal Shiny/DT examples in the issue and compare the Buttons, search box, and pagination control heights with and without bslib. Inspect the generated widget styling and verify that the affected controls align consistently in both layouts; done means the reported misalignment is resolved without requiring a custom theme.
