Suggest removing the backdrop dim/blur applied when the mobile sidebar is open

Description

When the mobile sidebar is opened, a .modal-backdrop overlay is appended that dims and blurs the page behind it:

.modal-backdrop{
    --bs-backdrop-bg:transparent; --bs-backdrop-opacity:1;
    background-color:color-mix(in srgb,var(--black) 10%,transparent);
    backdrop-filter:blur(4px); -webkit-backdrop-filter:blur(4px);
}

For a drawer that slides over the content (rather than a modal dialog), the dim/blur is visually unnecessary and can look heavy on long admin pages.

Expected

Consider not dimming/blurring the page behind the open mobile sidebar, or make it opt-in. Closing the drawer should not require the overlay to be visibly rendered.

Suggestions:

• Remove the backdrop-filter: blur and/or the translucent background, leaving the backdrop only as a transparent click-catcher (or dropping it entirely once click-outside-close is handled on document).

Workaround we use today (not viable upstream)

We remove the backdrop with a MutationObserver in our own JS and close the sidebar via a document click handler instead.

Environment

EasyAdmin v5.5.1 (@media (max-width:991px) responsive header / mobile sidebar).

Start by locating the mobile sidebar and .modal-backdrop styles used under @media (max-width:991px) in EasyAdmin v5.5.1, then reproduce the open-drawer behavior on a long admin page. Done means the drawer remains usable, the page is not visibly dimmed or blurred, and click-outside closing still works if the transparent backdrop is retained.
