Hi,

To reproduce:
1. Get a multilayered Krita kra file ( eg. https://www.peppercarrot.com/en/viewer/misc__2022-08-15_kiki-repairing_by-David-Revoy.html , it has three layers, link to the zip containing the kra in the footer).
2. Open in Krita a new document
3. Drag and Drop from your file explorer the Kra file on your canvas
4. At the contextual menu appearing, select "Insert as New Layer"

Result:
The content of the Kra files, its layers, are inserted on the stack but in reversed order: the bottom one will appear on the top, the top one on the bottom. It breaks the rendering. 

Expected: 
The layers to be inserted in the correct order.

Observation:
- It affects also 5.2.5, 5.2.3 but not 5.2.2 and before (tested via appimage thanks to https://download.kde.org/Attic/krita/ )
- I would appreciate (if possible/"low hanging fruit") to import the layers bundled inside a group (named after the filename). That would help at keeping the layer stack organized.
