Why does my webkit automation fall apart when the page takes 3 seconds to render?

been working on a safari scraper for a few weeks now and i keep running into this issue where the selectors i’m targeting disappear or shift around once dynamic content loads. the page renders fine visually but my automation just fails silently or times out. i’ve heard that ai copilot can generate workflows that adapt to this kind of thing, but i’m skeptical about whether it actually works in practice or if it’s just another layer of abstraction that breaks as soon as you deploy it. has anyone actually used an ai copilot to build something that handles webkit rendering delays without constant manual fixes? what does that workflow actually look like?
