Rendering issue when using build_article() and leaflet/tmap

[marine-ecologist]

I have an intermittent but reoccurring issue with pkgdown::build_articles() when trying to compile a vignette for a package.

As a reproducible example, I've uploaded a RMarkdown file to GitHub here along with the sf file (5.8mb).

The document renders fine with rmarkdown::render() but fails with pkgdown::build_articles() in that the process completes without errors but the resulting html fails for the map and all lines thereafter.

The problem occurs when using view mode on tmap:

tmap_mode("view") + 
  tm_shape(dfunitemethod) + 
  tm_lines()

and persists when the tmap object is converted to leaflet:

tmpplot <- [tm_shape](https://rdrr.io/pkg/tmap/man/tm_shape.html)(dfunitemethod) + 
  [tm_lines](https://rdrr.io/pkg/tmap/man/tm_lines.html)() 


tmpplot_leaflet <- [tmap_leaflet](https://rdrr.io/pkg/tmap/man/tmap_leaflet.html)(tmpplot, mode = "view")

The page and map render fine with tmap_mode("plot") and rmarkdown::render().

The issue seems to occur with multilinestrings, and I've checked with st_is_valid(NA_on_exception = TRUE, reason = TRUE) that the geometries are valid. These are fairly large datasets (1k MULTILINESTRINGS), but the error hasn't occurred on larger datasets with polygons or points.

I've also tried adding options(htmltools.preserve.raw = FALSE) to the code chunk to see if this fixes the issue, but nothing so far.

Suggestions on where to begin would be very welcome
