CacheKey reads filename first instead of pageName.

[darkwebdev]

Documentation states: cacheKey (String) - A unique String to use for cache reads and writes. Defaults to name.

Code disagrees:

if (!cacheKey) {
        cacheKey = input.filename || pageName; // Use the filename of the template as the cache key
}

I think cacheKey = pageName || input.filename; would make more sense.
