Removed section on Navbar Dropdowns for iOS due to z-indexing complexity. The `.dropdown-backdrop` class is no longer used anywhere and I don't think this issue exists.
There was a problem hiding this comment.
Pull request overview
Removes outdated iOS-specific documentation for navbar dropdown behavior, based on the fact that .dropdown-backdrop is no longer used in the codebase and the described z-index workaround is no longer relevant.
Changes:
- Removed the “Navbar Dropdowns” subsection from the iOS quirks area in the browser/device support docs.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

| As of iOS 9.2, while a modal is open, if the initial touch of a scroll gesture is within the boundary of a textual `<input>` or a `<textarea>`, the `<body>` content underneath the modal will be scrolled instead of the modal itself. See [WebKit bug #153856](https://bugs.webkit.org/show_bug.cgi?id=153856). | ||

| ### Navbar Dropdowns | ||

| The `.dropdown-backdrop` element isn’t used on iOS in the nav because of the complexity of z-indexing. Thus, to close dropdowns in navbars, you must directly click the dropdown element (or [any other element which will fire a click event in iOS](https://developer.mozilla.org/en-US/docs/Web/API/Element/click_event#Safari_Mobile)). | ||

Regrading Copilot's suggestion - I'd say remove that (https://deploy-preview-42424--twbs-bootstrap.netlify.app/docs/5.3/getting-started/browsers-devices/#overflow-and-scrolling) section too. It says that issue was fixed in Chrome in v40 and fixed in Safari 5 years ago. |
