WebP disappears when customizing Save Dialog File Formats
Photoshop does not display WebP in the Save As or Save a Copy format dropdown, even though WebP is enabled in Customize Save Dialog File Formats.
Steps to reproduce:
1. Open Customize Save Dialog File Formats.
2. Enable Photoshop, Large Document Format, PNG and WebP.
3. Save the customized settings.
4. Open Save As or Save a Copy.
5. WebP is missing from the available formats.
6. Return to the customization dialog and click Restore Defaults.
7. WebP becomes available again.
Expected result: WebP should remain available when enabled in the customized format list.
Actual result: WebP disappears with customized settings and reappears after restoring defaults.
Environment:
- MacBook Pro M4 Pro
- RGB Color, 8 Bits/Channel
- Document dimensions: 1200 x 900 px
Workaround: Restore Defaults restores WebP availability.
