The cosmetic filtering data embedded in the content scripts has been extracted in corresponding JSON files. When a list is enabled, the corresponding cosmetic filtering data from the JSON files, if any, is persisted into the extension's local storage. The cosmetic filtering-related content scripts will load the data from these JSON files on-demand only and matching cosmetic filters will be extracted, then the result is cached in the session storage, ensuring there is no longer a need to perform lookup for the rest of the browser session. As a result this further reduces the time to First Contentful Paint. Related issue: https://github.com/uBlockOrigin/uBOL-home/issues/557
