Hi!

I'm experiencing an issue that I believe to be a bug. The gist of it is this:
When mixing formbuilder elements (i.e. f.input calls) with arbre elements (e.g. strong 'something') within a form block, the output looks as expected: arbre elements that are specified between two input elements show up between the two elements in the markup.
When moving the very same code to a .html.arb partial, the behavior is different: suddenly all the arbre elements appear after all of the form inputs.

I've created a repository to show the issue: https://github.com/ncathor-gst/activeadmin-arbre-partial-bug

On the main branch, everything works as expected. The posts form looks like this:

Note how "Some text 1" and "Some text 2" are before and after the two checkboxes (expected).

On the partial branch, the code from the form block was moved to a partial and the posts form simply renders that partial (passing in the form builder f). Now it looks like this:

Note how "Some text 1" and "Some text 2" are now rendered after the entire form (not expected).
