Steps to reproduce:
1. Create a new project
2. Install the PSD Importer package
3. Download the attached "bugdemo.zip"
4. Drag the file "step 1/demo.psb" (from the attached bugdemo.zip file) into the project, then click on it and observe the preview: observe that it looks the same as it does in Photoshop (three numbered squares, aligned horizontally)
5. Right-click that PSB and do "show in explorer"
6. In windows explorer, copy the file "step 2/demo.psb" onto the "demo.psb" in the project, replacing it (to simulate a change to the existing file)
7. Return to the Editor window, and observe the preview of the updated file: observe the difference it now has from how it appears in Photoshop: the three boxes should still be aligned, with two circles emerging from either side of the middle box; instead, the middle box is misaligned, and the circle on its right side is missing
8. To further demonstrate the problem, now copy "step 2/demo.psb" into the Unity Editor window, to make it show up as a new asset (which will automatically be named "demo 1" by the editor). Notice that this NEW asset now does perfectly match how it appears in photoshop
Expected results: PSD importer plugin responds to changes in layer size
Actual Results: PSD importer plugin doesn't respond to changes in layer size
Reproducible in: PSD Importer 6.0.7 (2021.3.27f1), PSD Importer 8.0.2 (2022.3.2f1), PSD Importer 9.0.0 (2023.1.0f1, 2023.2.0a18)
Environment tested on: Windows 10
Notes:
-this bug only occurs when a layer is CHANGED; it does NOT occur for a document's INITIAL import. You can now click back and forth between the two files in the editor to more clearly notice the difference, even though the two .PSB files are identical on disk.
