Align the fonts displayed on the rich text editor canvas with fonts in the theme settings
Within the rich text editor interface the fonts for text displayed on the editing canvas do not align with those configured for the theme. As standard it seems that Georgia is shown as the paragraph font, for example, even if Arial is set as the default theme font for paragraphs within the theme.
Whilst fonts show up correctly on the front-end, this creates a disjointed and unprofessional-looking editing experience and can lead to errors.
For example, an editor may mistakenly believe that the font will display incorrectly on their landing page, based on what they can see in the rich text editor, and so change the font manually in the rich text editor. This places the 'correct' font as an inline style. This will lead to maintainability issues down the line if, for example, the theme fonts do change.
