Clean Files Optimization Feature and Chrome Browser Cache

I have the strong impression that Support Assist Clean Files optimizer deletes browser temporary files externally in the OS to Chrome, and that the browser thus does not know the cache has been cleared, leading to issues. Unless you immediately after the optimization go into Chrome and use the 'More Tools' -> 'Clear Browsing Data' -> 'Cached Images and Files' to clear this cache completely in Chrome, every web page you look at will (on first use) experience a "Flash of Unstyled Content' etc problem which will have to be resolved by refreshing the page - because Chrome thinks the cache is still there.
