Gavin, since this bug has been transformed into something I did not think it was about (which would indeed be the
loading="lazy" attribute, for lazy-loading images and iframes) I'm not sure if my concerns apply here. This bug was brought up on our forum in tandem with:
which, as I understand it now, is incorrect.
My main concerns with this are:
- Lack of actual loading of monetization elements if they aren't in view. Many ad services use impressions as a main statistic to pay revenue. This will be severely cut if lazy loading prevents server hits. I don't think that's healthy for the already damaged display ad industry and will push website owners to more intrusive methods of advertising.
As said I'm not sure to what extent this applies to your sponsored content on your new tab page, but even if using normal front-end methods I'd gather similar concerns should be kept in mind.
