[DatacoreJSX] Embedded block inside hover preview reads parent file's frontmatter instead of embedded file's

[ichris007]

Description

I have a DatacoreJSX dashboard that reads frontmatter from the "active file". I embed this dashboard into candidate files. When I hover over a link to these candidate files from a parent file, the dashboard incorrectly reads the parent file's frontmatter.

File Structure

parent.md                          ← has its own frontmatter
    └── [[candidate.md]]           ← hover preview triggers here
              |
              └── candidate.md     ← has candidate-specific frontmatter
                    └── ![[dashboard.md]]   ← embedded DatacoreJSX

dashboard.md

const targetFile = app.workspace.getActiveFile();
// expects to read candidate.md's frontmatter
// but in hover preview, gets parent.md

candidate.md

---
status: "Interviewing"
talent: "John Doe"
---

![[dashboard.md]]

parent.md:

---
# unrelated frontmatter
---

Check candidate: [[candidate.md]]

Expected Behavior

When I hover over [[candidate.md]] in parent.md, the popup preview should show candidate.md's data (status: "Interviewing", talent: "John Doe").

Actual Behavior

The popup shows parent.md's frontmatter (empty or unrelated data).

Question

How can I make the embedded DatacoreJSX block always read the file that contains the ![[...]] embed, regardless of whether it's being viewed directly, embedded, or hover-previewed?

What I've Tried

Using app.workspace.getActiveFile() – fails in hover preview context

Using dc.useActiveContext() – same issue

Request

Is there an API to get the "embedding file" rather than the "active file"?

Or a way to detect hover preview mode and get the correct file reference?
