opt_interactive does not seem to be working

[duncangates]

Description

I have tested on my local computer, shinyapps.io, and Posit Cloud and have found that opt_interactive currently displays nothing in the table content itself

Reproducible example

From the documentation for gt::opt_interactive()

# install.packages("gt") # if needed
library(gt)

towny |>
  dplyr::select(name, census_div, starts_with("population")) |>
  gt() |>
  fmt_integer() |>
  cols_label_with(fn = function(x) sub("population_", "", x)) |>
  cols_width(
    name ~ px(200),
    census_div ~ px(200)
  ) |>
  tab_header(
    title = "Populations of Municipalities",
    subtitle = "Census values from 1996 to 2021."
  ) |>
  tab_source_note(source_note = md("Data taken from the `towny` dataset.")) |>
  opt_interactive()

Expected result

An interactive table should be created, instead the table appears to have no content asides from the title and subtitle.

Updating to htmlwidgets 1.6.4 fixes the issue.
