version_tooltip doesn't seem to work as expected.

I found one notable usage in the wild: the data.table package

https://github.com/Rdatatable/data.table/blob/master/_pkgdown.yml

However, the tooltip doesn't appear on their website. https://rdatatable.gitlab.io/data.table/

I couldn't find a way to make it work.

I tried to set it for tmap, r-tmap/tmap@5568c3d

but still shows the default in https://r-tmap.github.io/tmap/dev/

It looks like the setting in the config file isn't respected, set here:

pkgdown/R/render.R

Line 125 in 812e8c8

out$development$version_tooltip <- version_tooltip(pkg$development$mode)

May just need to check for a value before setting?

I don't have time to get this done today, I don't think it's that important, and we're likely to do a patch release in a few weeks, so I'm pushing this to the next release.
