[FIX] web_editor: ensure correct fonts are used

Since commit [1], the new tiktok icon is added to odoo but the
conversion of the css class into an image is not supported.

This commit ensures that the conversion is correctly handled.

Steps to reproduce:
- Open the mail marketing app
- Create a new mass mailing
- Insert an icon in the template, for instance type /image in the text
  and select the "Pictogram" tab
- Search for tiktok icon and insert it
- Send the mass mailing
- The icon will not be found in the mail
