A prime example: JIRA's backlog view. In the self-hosted version, you could easily find the issue you were looking for in the backlog view by just using the browser's search, press Ctrl+F, write some words, you have the issue you were looking for. The cloud version Atlassian forced their users into, OTOH, features their own implementation hijacking Ctrl+F combined with dynamically removing the issues not currently visible from the DOM, to ensure that no-one can have the convenience of the browser's built-in search.
