ACF header floats over the WordPress mobile admin menu and blocks top menu items

Assessment

Research direction

Description

Describe the bug
On mobile breakpoints, opening the WordPress admin navigation menu causes .acf-headerbar to remain static and float directly on top of the opened sidebar menu. This visually covers the top sidebar menu items (such as "Dashboard") and intercepts clicks/taps, preventing the user from interacting with those links.

To Reproduce
Steps to reproduce the behavior:

1. Go to any ACF admin screen in the WordPress dashboard (e.g., ACF > Field Groups, Post Types, Taxonomies, or Tools).
2. Resize the browser viewport to a mobile width (600px or less), or inspect using device mode (e.g., iPhone at 375px–390px).
3. Click/tap on the hamburger menu icon (#wp-admin-bar-menu-toggle) in the WordPress admin toolbar to open the admin sidebar menu.
4. Observe that the ACF header bar (.acf-headerbar) floats above the top of the open sidebar menu, obscuring links like "Dashboard" and blocking clicks.

Expected behavior
When the mobile admin menu is open, the ACF header bar should not overlap the sidebar menu, allowing users to access and click all menu options without obstruction.
