Does this fix it? I would think that adding a line here would not help attach the warning to the text.

Yes. It does. I faced something similar when generating https://github.com/cstjean/ScikitLearn.jl/edit/master/docs/src/man/models.md.
You can also confirm this by comparing https://github.com/JuliaLang/julia/blob/master/doc/src/manual/types.md#primitive-types with https://github.com/OkonSamuel/julia/blob/master/doc/src/manual/types.md#primitive-types.
The github diffs don't show the difference clearly. You have to open the two links to see.

@mortenpi, is this a Documenter bug? I'm a bit confused by what the right way to format/fix this is.

[mortenpi]

No, it's an indentation problem on the 1.5 branch. It's already fixed on master: https://docs.julialang.org/en/v1.6-dev/manual/types/#Primitive-Types-1

The correct fix would be to backport #36254 to 1.5.

For what it's worth, as a style matter, I personally prefer having an empty line between the !!! line and the admonition body, so we could merge this, even if it doesn't actually do anything for #36878.
