As a quick fix for this bug, the partial revert of the related ticket is done (see related PR: https://gitlab.magnolia-platform.com/pd/platform/ui/-/merge_requests/3019). After this the png thumbnails will be again rendered using imaging module with proper server-side caching applied (as well as in the browser). This will cause minor regression of the visuals of thumbnails with alpha-layer. The proper solution for the regression has to be done in the scope of the re-opened MGNLUI-8938.
