Embedded Layers still reference remote layer in the packaged QField Project

[legnad]

Describe the issue

I have a QGIS project which contains multiple embedded layers from a different project file. There are PostGIS, WMS, TIF among them. The PostGIS layers only work when setting them to "Offline editing". "Directly access data source" and "Copy" are not working, which applies to the embedded TIF and WMS layers too.

Reproduction steps

Steps to reproduce the behavior:

1. Embed (e.g. PostGIS or WMS) Layer
2. within QField Cloud Sync set it to "Directly access data source"
3. export package with QField Sync
4. import to QField

Expected behavior

Load and show features/rasters/layers.

Observed behavior

Layer ist either missing completely (in list) or showing nothing (no raster/feature) on the canvas at all. Log messages indicate a reference to the other project file from which the layers are embedded from: Error zip file does not exist: '<<relative path to _remote_ qgis project>>.qgz'
