The message have only defined the text colour and not the background. So the text colour is set by the style in the message but the background is set by TB depending of dark/light theme.

We have already other such bugs.

This is related to bug 1659362. With pref mail.html_sanitize.drop_conditional_css set to false, the text is legible.
