Overview

Reopens ActiveAdmin::Views::SidebarSection (used for every sidebar section, e.g. "Filters", "Search Status", any custom sidebar :title do ... end block) to inject a real inline SVG icon into the title of the Filters section specifically — matching the id ActiveAdmin::SidebarSection#id computes for it ("filters_sidebar_section"). Every other sidebar section is untouched.

The label text is wrapped in its own span so CSS can visually hide it while collapsed without touching the icon (see scss-src/_panels.scss's #filters_sidebar_section rules, and prism.js's filters-collapse handler for the actual toggle).

This only runs when ActiveAdminPrism.configuration.collapsible_filters is true — when it's false the section is left exactly as ActiveAdmin renders it by default (plain text title, no icon).

    # Panel#build already appended the plain-text @title (h3) as the
    # first child, followed by @contents (the panel_contents div).
    # Replace it with an [icon, label-span] version — built fresh
    # rather than mutated in place (Arbre elements don't expose an
    # API to insert content before an existing child).
    #
    # Panel#add_child redirects *any* add_child call on this object to
    # @contents once @contents exists (so plain builder calls inside a
    # panel's do-block land in .panel_contents, not as top-level
    # siblings) — building a fresh h3 via the normal `h3(...)` verb at
    # this point would silently land *inside* .panel_contents instead
    # of replacing @title. Building it while @contents is
    # (temporarily) nil bypasses that redirect — but add_child still
    # *appends* (to the end of `children`, after the contents div,
    # since that div itself is still sitting in `children` even
    # though the @contents variable is momentarily nil), so it has to
    # be explicitly deleted from wherever it landed before unshifting
    # it to the front — otherwise it ends up in `children` twice.
