Is it possible to do the following:
Given a route such as /foo/[slug] with +page.js in it to load some data based on the slug, can the data be kept when navigating to /foo/[slug]/bar and available in the +page.svelte? The context of this is that there is some file being loaded to render on /foo/[slug] and that same file is used on /foo/[slug]/bar, so having the file preloaded is ideal. This approach would also require the file being loaded if /foo/[slug]/bar is visited first. I believe that load functions perform dependency checking. Reading through the docs, especially under the section about running the parent load function, it seems like this should be possible, but I can’t quite figure it out.
Some approaches that would work are to use stores, or to use the layouts option, but is there a simpler approach?
I’ve tried getting the page data on the nested page directly, but it results in an empty object instead of the content from the /foo/[slug] page, which suggests that the data is not being loaded properly.
