@andrew.mcdonagh Yep, no native solution yet, and I wouldn’t hold my breath for one either. This is less of a Bubble limitation and rather a common issue in web dev generally i.e. knowing when items have actually been “painted” in the browser (when a page is built with javascript, as is the case with Bubble). Bubble’s “is loading” state only returns true while it is fetching data from the database, and there can be a huge lag between the data being returned and the actual element being displayed on screen.
I’ve been working on a solution that may interest you
