SilverStripe Tinymce configuration not updating inside module - php

Question

We have a boilerplate module that we include on all of your SilverStripe builds. We are attempting to add a new class to our customised WYSIWYG config.
The weird thing is that we have a module dedicated to this but as soon as we move this configuration out of that module and into the new module, the config reflects only a couple of the changes and not all.
Example:
wysiwygboilerplate/_config.php
companyname-boilerplate/_config.php
The first example shows the correct wysiwyg configuration. When that same code is moved to the new location 'companyname-boilerplate/' directory it ceases to function.
This is the snippet of code I am working with. (with the only update being the path to content css)
//-------------------------------------------- WYSIWYG config
$defaultEditorConfig = HtmlEditorConfig::get('cms');
$defaultEditorConfig->setOptions(
array(
'theme' => 'advanced',
'priority' => 1,
'browser_spellcheck' => true,
'body_class' => 'wysiwyg',
'content_css' => '/companyname-boilerplate/styles/wysiwyg.css',
'schema' => 'html5',
'extended_valid_elements' => 'figure,figcaption',
'end_container_on_empty_block' => true,
'style_formats' => array(
array(
'title' => 'H1',
'block' => 'h1'
),
array(
'title' => 'H2',
'block' => 'h2'
),
array(
'title' => 'H3',
'block' => 'h3'
),
array(
'title' => 'H4',
'block' => 'h4'
),
array(
'title' => 'H5',
'block' => 'h5'
),
array(
'title' => 'Paragraph',
'block' => 'p'
),
array(
'title' => 'Blockquote',
'block' => 'blockquote',
'wrapper' => true
),
array(
'title' => 'Figure',
'block' => 'figure',
'wrapper' => true
),
array(
'title' => 'Figure caption',
'block' => 'figcaption',
'wrapper' => true
)
)
)
);
$defaultEditorConfig->disablePlugins('contextmenu');
$defaultEditorConfig->enablePlugins('lists', 'paste');
$defaultEditorConfig->setButtonsForLine(1, 'styleselect, formatselect, separator, bold, italic, separator, justifyleft, justifycenter, justifyright, separator, bullist, numlist, separator, charmap, ssmedia, separator, sslink, unlink, separator, code');
$defaultEditorConfig->setButtonsForLine(2);
$defaultEditorConfig->setButtonsForLine(3);
My initial thoughts are that this is to do with the order SilverStripe is loading the configuration files, but there are no other files / modules that define a HtmlEditorConfig that I am aware of.
The other thought I had was around caching, I cleared out the SilverStripe cache, my browser cache and even ran a dev/build with still no joy, so that rules out caching

Answer 1

As the modules config are included in alphabetical order you either have to rename your boilerplate module (or the installation dir in composer.json) that it comes after framework or put the config inside mysite manually, cause mysite is added at last and there you can overwrite settings.
