some selected rows loose bg (bootstrap 5, rowGroup extension, selection)

[guasi]

In a datatable with grouped rows, when an even row is selected in the odd groups, the selected row looses its background color when the cursor moves out of the row.

This only happens when using bootstrap 5 via bslib, extension loads rowGroup, and selection is single or multiple.

Example:

  library(shiny)
  library(DT)
  
  dat <- data.frame(type = sort(rep(c("A","B","C","D"),5)), value = rnorm(20))
  
  ui <- bootstrapPage(
    theme = bslib::bs_theme(
      version = 5
    ),
    DTOutput("table")
  )
  
  server <- function(input, output) {
    output$table <- renderDT({
      datatable(
        dat,
        extensions = "RowGroup",
        selection = "single",
        options = list(
          dom = "t",
          pageLength = 20,
          rowGroup = list(dataSrc = 1)
        )
      )
    })
  }
  
  shinyApp(ui, server)

The screenshot shows what happens after I select row 12 and then move away from the row. Row 12 looses its backgroup color. The screenshot shows row 12 (even row), under the C group (odd group) to be blank. The interpreted css sets box-shadow: none to the selected row when it should not.

This does not happen when using previous versions of bootstrap in the same set up as defined above. Also it does not happen when using just the DataTable library (bootstrap-5-5.3.0, DataTables-1.13.8, JQuery-3.7.0, RowGroup-1.4.1).
