`save_map(hide_controls = TRUE)` does not reliably hide controls when using `add_pmtiles_source()`

[danielvartan]

Summary

mapgl::save_map() hides map controls correctly for many maps, but when the map includes a PMTiles source via add_pmtiles_source(), controls can still appear in the exported PNG even with hide_controls = TRUE.

Reproducible Example

library(mapgl)

map <- 
  maplibre(
    bounds = c(-73.99045, -33.75118, -28.84764, 5.271841)
  ) |>
  add_pmtiles_source(
    id = "state_boundaries",
    url = "https://tiles.pmtiles.com.br/geobr/read_state/code-all-year-2020-simplified-TRUE-min_zoom-2-max_zoom-10.pmtiles"
  ) |>
  add_fill_layer(
    id = "fill",
    source = "state_boundaries",
    source_layer = "read_state",
    fill_color = "blue"
  ) |>
  add_navigation_control()

map |>
  save_map(
    filename = "pmtiles_map.png",
    hide_controls = TRUE
  )

Expected Behavior

Controls are hidden in the output image when hide_controls = TRUE.

Actual Behavior

When PMTiles is used, some controls remain visible in the saved image.
