Viewer doesn’t show checkered background for cutouts without optimisedPng #3997
Description
Short description
Because checkered background depends on the presence of optimisedPng, it won’t show for images with transparency which do not have one (eg. 8bit transparent PNGs).
Steps to reproduce
Upload or find 8bit PNG with transparency (no optimisedPng in the API response, eg. 98e1b3a1464bb226d11d700c47268b1f8b1c2b30 in PROD).
Actual results
Observe lack of checkerboard background for main image preview.
Expected results
Checkerboard background should show for all images with transparency.
