Do you use reply by email often, as I thought HtmlToMarkdown was only utilized by incoming emails. Here is my spec (which @sam graciously wrote when upgrading to the new markdown engine)
```ruby
require 'rails_helper'
describe PrettyText do
context 'markdown it' do
before do
SiteSetting.enable_experimental_markdown_it = true
end
it 'can properly bake boxes' do
md = <<~MD
[],[],[_];[-]X[x]X [*] [\\*] are all checkboxes
`[]` [x](hello) *[]* **[]** are not checkboxes
MD
html = <<~HTML
,,;XX are all checkboxes
[] x [] [] are not checkboxes
HTML
cooked = PrettyText.cook(md)
expect(cooked).to eq(html.strip)
end
end
end
```
And my whitelist that seems to work both server-side and client-side
```plaintext
export function setup(helper) {
helper.whiteList([ 'span.chcklst-stroked',
'span.chcklst-box fa fa-square-o',
'span.chcklst-box fa fa-square',
'span.chcklst-box fa fa-minus-square-o',
'span.chcklst-box checked fa fa-check-square',
'span.chcklst-box checked fa fa-check-square-o' ]);
}
```
