PATH_MAX still an issue despite Windows setting allowing longer paths
Rendering Quarto chunks errors if path is too long, (but confusingly enough not an issue when rendering the entire document using the Render-button or through the quarto-package). I have already set Windows 11 to allow extended filepaths. After some digging it seem that fs is clinging to old MAX_PATH/PATH_MAX behaviour, even though libuv removed this limit in 2020.

P.S. Trying to roll out Quarto to my organization coming weeks and months and there is no alternative with shorter (relative) paths, so would be superbly happy for a fix soon.
Similar problem here: I have long paths enabled in Windows but get:
> fs::dir_copy(wd, outdir, overwrite = FALSE)
Error in path_tidy(.Call(fs_path_, lapply(args, function(x) enc2utf8(as.character(x))), :
Total path length must be less than PATH_MAX: 260
I am not sure as to even why I get the problem, because my longest paths seem to be shorter than PATH_MAX:
> a <- list.files(wd, full.names = TRUE, recursive = TRUE)
> b <- gsub(topattern(wd), outdir, a) # (topattern = homebrew function to convert a string to a regex pattern)
> max(nchar(a))
[1] 252
> max(nchar(b))
[1] 237
