ISSUE
Wishlist and Ignore effects that are on top of bundled products' thumbnails will only display over the "first" product in the bundle. The Ignore faded-out effect seems to display correctly.

OS
Windows 10, probably irrelevant

STEPS
1. Launch Steam
2. Find a game that's bundled with another - in this case we'll use the MakeRoom X House Flipper bundle.
3. Add MakeRoom to your wishlist.
4. Add House Flipper to your Ignored list.
5. Go to MakeRoom's store page.
6. Notice that in the House Flipper x MakeRoom bundle section, House Flipper will now have the Wishlist icon and Ignored icon on top of each other, and also its thumbnail is faded out like an Ignored product would be usually ( https://imgur.com/a/ACSgVTt - top image).
7. The Ignore icon on House Flipper will display correctly once you remove MakeRoom from your Wishlist.
8. Remove MakeRoom from your wishlist.
9. Add MakeRook to your Ignored list.
10. Remove House Flipper from your Ignored list.
11. Add House Flipper to your wishlist.
12. Return to MakeRoom's store page.
13. Now the thumbnail for House Flipper will feature the Wishlist star correctly. MakeRoom will be faded out as an Ignored product should be, but the Ignore icon is nowhere to be found (bottom image in the imgur link in step 6).

(the order for steps 3-4 and 8-12 is not important)

From my testing it appears to make no difference which product you are viewing the bundle from.

RESULTS
Minor issues with displaying Wishlisted and Ignored effects over thumbnails of each product in the bundle widget when viewed from the page of a product that's part of the bundle

EXPECTED
The Wishlisted and Ignored effects are displayed correctly over each thumbnail in the bundle widget when viewed from the page of a product that's part of the bundle
