fix: lazy check for available product links

[dhhyi]

PR Type

[x] Bugfix

What Is the Current Behavior?

If the property displayOnlyAvailableProducts is activated on ish-product-links-carousel, the component fetches all linked products to calculate the carousel content. This leads to a drop in page performance, especially in SSR if products have many linked accessories.

What Is the New Behavior?

The product links are evaluated lazy slide by slide whenever the user switches to them. For SSR only the first slide is evaluated.

Does this PR Introduce a Breaking Change?

[ ] Yes
[x] No

@dhhyi
I linked 7 accessory products to a product, one of them is not available.
If I scroll to the left and after that to the right so products become visible again I experience the following issues:

• the image of these products are not visible immediately so that the no-image-available image is to be seen shortly
• the product prices for these products are (unnecessarily) fetched from the REST api

Is there any chance to fix these issues?

@SGrueber

Is there any chance to fix these issues?

Yes, this behavior was caused by tearing down and re-initializing product contexts. This is now fixed by preserving the slides that have already been viewed.
