Actually (as of a few versions ago) bundles do actually highlight using a similar method to the one you've described. Rather than scraping the SteamDB, Enhanced Steam actually scrapes the store page for a bundle and retrieves a list of AppIDs that it contains. Doing it this way means that not only do I not have to keep a list, but it also works with region-restricted stuff as well.
So if you own everything in the (for example) Alan Wake Franchise Pack and do a search for Alan Wake it should correctly highlight the bundle as owned.
Unfortunately it doesn't do this on the Halloween sale page because Valve broke away from their traditional coding methods (once again) which requires me to redirect the div that's highlighted. I'm right in the middle of a huge code conversion so I wasn't able to push out a patch while the sale was going on unfortunately.
That's super to hear--very smart solution. Immediately after I posted I stopped and said "wait, regional content!" and your solution solves that. Good job as always, and we're lucky to have you as a part of the community.
