This bug was fixed in the package apache2 - 2.4.29-1ubuntu1

---------------
apache2 (2.4.29-1ubuntu1) bionic; urgency=medium

  * Merge with Debian unstable. Remaining changes:
    - debian/{control, apache2.install, apache2-utils.ufw.profile,
      apache2.dirs}: Add ufw profiles.
    - debian/apache2.py, debian/apache2-bin.install: Add apport hook.
    - debian/patches/086_svn_cross_compiles: Backport several cross
      fixes from upstream
    - d/index.html, d/icons/ubuntu-logo.png, d/apache2.postrm: replace
      Debian with Ubuntu on default page.
      + d/source/include-binaries: add Ubuntu icon file
    - Correct systemd-sysv-generator behavior by customizing some
      parameters:
      + d/apache2-systemd.conf: add a drop-in file to specify some
        parameters for the systemd unit (type=Forking and
        RemainsAfterExit=no), this allow a correct state synchronisation
        between systemctl status and actual state of apache2 daemon.
      + d/apache2.install: place the apache2-systemd.conf file in the
        correct location.
    - Don't build http2 module (nghttp2 still not in main) (LP 1687454)
      + debian/control: removed libnghttp2-dev Build-Depends (in universe).
      + debian/config-dir/mods-available/http2.load: removed.
      + debian/rules: removed proxy_http2 from configure.
  * Switch back to OpenSSL 1.0 as we don't yet have 1.1:
    - debian/control: switch BuildDepends to libssl1.0-dev
    - debian/control: remove Breaks on gridsite and libapache2-mod-dacs
    - debian/rules: remove openssl virtual package and logic
