Why don’t browsers mask out events during render of page regions or note their time and bounding boxes so click events reach the correct element?

Steps to reproduce this annoyance:

- visit Twitter mobile site: mobile.twitter.com in Safari on a slow iPhone (eg iPhone 6 stuck on iOS 12.X). - scroll and view tweets for a while soaking up memory. - visit a tweet - press tweet share icon - popup menu takes forever to render fully to include the Cancel button. - clicking Bookmark tweet menu item will trigger item after that, Copy Link to Tweet, when it finally loads and moves that menu item under your finger.
