Pressing Ctrl+F selects the site’s search box for input, hijacking the browser’s built-in functionality.
Please remove the JS function that hijacks the browser’s built-in functionality. If someone want to search the website, let them click on the search box (or use tabindex). I believe the browser should always function as expected.
In topics with more than a certain number of posts, Discourse (the software behind this site) doesn’t load every single post right away, but rather lazy-loads as you scroll. The browser search would not be accurate in those cases, which is why Discourse hijacks the search function on those pages (and only on those - it falls back to the browser search on regular pages or threads with a small number of posts).
