Error: Call to a member function getConfigDependencyName() on null

Problem/Motivation

Steps to reproduce:

1. A fresh installation of Drupal 8.8.x
2. Install 8.x-1.x version of this module (commit: 9c861dd4452a28b8312674e89292a41fb4652d66 as writing)
3. Export config drush cex
4. Get site UUID, drush cget system.site uuid
5. Install again
6. Set site UUID drush cset system.site uuid THE-UUID-GOT-AT-STEP-4
7. Delete shortcut entities so that it's possible to import the config exported at step 3. drush edel shortcut
8. Import config, drush cim -y
9. Bingo
   

   Import the listed configuration changes? (yes/no) [yes]:
    > yes
   
    [notice] Synchronized extensions: install embed.
    [notice] Synchronized extensions: install entity_browser.
    [notice] Synchronized extensions: install entity_embed.
   Error: Call to a member function getConfigDependencyName() on null in Drupal\Core\Entity\EntityDisplayBase->calculateDependencies() (line 325 of /Users/jungleran/www/8.8.x/core/lib/Drupal/Core/Entity/EntityDisplayBase.php).
    [warning] Drush command terminated abnormally. Check for an exit() in your Drupal site.

Furthermore:

1. Apply the patch mentioned in #6, 📌 calculateDependencies doesn't check $mode_entity if it is NULL Needs work , but the latest one, in #28

   curl https://www.drupal.org/files/issues/2019-12-16/2741429-2-28.patch | git apply 
   

   Repeat the steps above, run twice drush cim,

   The first time you will get the error

    // Import the listed configuration changes?: yes.                                                                      
   
    [notice] Synchronized extensions: install embed.
    [notice] Synchronized extensions: install entity_browser.
    [notice] Synchronized extensions: install entity_embed.
   
   In ConfigImportCommands.php line 261:
                                                      
     The import failed due to the following reasons:  
   
   config:import [--preview [PREVIEW]] [--source SOURCE] [--partial] [--diff] [-h|--help] [-q|--quiet] [-v|vv|vvv|--verbose] [-V|--version] [--ansi] [--no-ansi] [-n|--no-interaction] [-d|--debug] [-y|--yes] [--no] [--remote-host REMOTE-HOST] [--remote-user REMOTE-USER] [-r|--root ROOT] [-l|--uri URI] [--simulate] [--pipe] [-D|--define DEFINE] [--notify] [--druplicon] [--xh-link XH-LINK] [--] <command> [<label>]
                                                      
   

   No clues.

2. But visit /admin/reports/dblog, you will see a config_import type message below:

   
   Drupal\Core\Config\Entity\Exception\ConfigEntityDependencyDoesNotExistException: Cannot add the config entity dependency with ID 'node.content_browser' of type 'entity_view_mode' to core.entity_view_display.node.article.content_browser as it does not exist in Drupal\Core\Config\Entity\ConfigEntityBase->addConfigEntityDependency() (line 645 of /Users/jungleran/www/8.8.x/core/lib/Drupal/Core/Config/Entity/ConfigEntityBase.php).
