Cross-Version: Pattern Overlay Layer Style: Linear Light Blending Mode set in 27.2 Reverts to Normal

When a Pattern Overlay layer style is configured with "Linear Light" blending mode in Photoshop 27.2 and the file is saved, the blending mode is not preserved when opening the file in older Photoshop versions or the current Beta version. The blending mode automatically reverts to "Normal" instead.

We're working on macOS Sequoia 15.7.3 on Apple Silicon. PS Version 27.2 is affected.

Steps to Reproduce:

1. Open Photoshop 27.2
2. Create a new document with a layer
3. Apply a Pattern Overlay layer style to the layer (Layer > Layer Style > Pattern Overlay)
4. Set the Blending Mode of the Pattern Overlay to "Linear Light"
5. Save the file as .PSD
6. Open the same file in either:
   • An older version of Photoshop (pre-27.2)
   • The current Photoshop Beta version

Expected Behavior:
The Pattern Overlay layer style should maintain its "Linear Light" blending mode setting when opening the file in different Photoshop versions.

Actual Behavior:
The Pattern Overlay blending mode automatically changes from "Linear Light" to "Normal" when the file is opened in versions other than 27.2.

Impact:
This breaks cross-version compatibility and workflow consistency for teams working with different Photoshop versions or users testing Beta releases. Layer style appearance changes unexpectedly, requiring manual corrections.

Additional Notes:
This doesnt happen to other blending modes as far as we see.
