0045564: Service workers infrastructure precaches CSS files that are then never used

DescriptionCurrently there is code inside the Service workers/AppCacheManifest infrastructure that adds CSS files belonging to external modules automatically to the Manifest as separate requests: method getcssFileList()
cache-manifest-ftl <#list data.cssFileList as cssFile>

This causes the Service Worker to request and store those files separately. However, the WebPOS application then never formally requests them, as their content is already present inside the main StyleSheetResources request.

Therefore, we are wasting quite a bit of bandwidth and triggering many unnecessary requests.
Steps To ReproduceGo to livebuilds and access the modules instance. Check in developer tools and see that many css requests exist separately, coming from the Service Worker.

Then reload the page (F5), and realise that those css files are never actually requested by the application.
Proposed SolutionDelete both the getcssFileList method inside and the corresponding CSS section inside cache-manifest-ftl
