DT Datatable with selectInputs resets back to left after selection

I am using selectInputs in a column of a DT datatable in a Shiny app. Thanks to some help here, I am including some JavaScript to selectize the selectInputs to keep the style and search capability of selectize. It is a wide table, so the selectInputs require scrolling horizontally to see them.

When I make a selection in any of the selectInputs the first time, everything works fine. However, when I click any of the selectInputs a second time, the page scrolls back to the left and the selectInputs are out of view. How can I keep the style and search capability I have but prevent this from happening?

EDIT: I also tried using shinyWidgets::pickerInput, and it does not have the scrollbar problem. However, the liveSearch feature does not work for me in a datatable. If you can solve that issue, I'll consider this question answered.

Example:

library(shiny)
library(DT)

# Function to selectize one or more input ids
selectize_ids <- function(ids) {
  myStrings <- as.character(sapply(ids, function(id) {
    paste0("  $('#", id, "').selectize();")
  }))
  c(
    "function(settings){",
    myStrings,
    "}"
  )
}

shinyApp(
  ui = fluidPage(
    div(style = "display: none;", selectInput(inputId = "dummy", label = NULL, choices = 1:2)),
    fluidRow(DT::dataTableOutput("mytable"))
  ),
  server = function(input, output, session) {
    df <- as.data.frame(matrix(data = paste0("text", 1:60), ncol = 20))
    colnames(df) <- paste0("column", 1:ncol(df))
    df$myselect <- sapply(1:nrow(df), function(i) {
      as.character(selectInput(
        inputId = paste0("myselect_", i),
        label = NULL,
        choices = c("option1", "option2", "option3")
      ))
    })
    select_ids <- paste0("myselect_", 1:nrow(df))
    output$mytable <- DT::renderDataTable({
      DT::datatable(
        data = df,
        escape = F,
        options = list(
          initComplete = JS(selectize_ids(select_ids))
        )
      )
    })
  }
)
