Folder preview thumbnails that haven't been generated yet showed a loading spinner that never resolved.
There are two root causes:
For
origin=folderPreview, noAssetPreviewImageMessagewas dispatched and the placeholder response lackedCache-Control: no-store, causing the browser to cache it permanently.The
_dc=modificationDatecache-buster meant the browser never re-fetched pending thumbnailsThis PR fixes both.
