Quarto only renders 16 mapgl objects

[baslat]

I have a Quarto document with multiple mapgl objects, however only the last 16 are rendered. Reprex is below. If I swap maplibre() for mapview::mapview() all 20 objects are rendered, which makes me think it's related to mapgl and not htmlwidgets. Any advice?

Reprex:

---
title: "20 test"
format: html
---

```{r}
#| echo: false
library(mapgl)
sessionInfo()

nums <- seq_along(1:20)
```

# 20 maps?
```{r}
#| results: asis
#| echo: false
nums |>
	purrr::map(\(x) {
		knitr::knit_child(
			text = c(
				"# `r x`",
				"```{r}",
				"#| echo: false",
				"maplibre()",
				"```"
			),
			envir = environment(),
			quiet = TRUE
		)
	}) |>
	unlist() |>
	cat(sep = "\n")
```

We've hit this before in leafgl.
This is a hard limit of (some?) web browsers for webgl, so there's not much one can do on the package side.

See openlayers/openlayers#12800 for another similar issue in openlayers.
