I am using Thunderbird 78.7.1 (64-bit) on Ubuntu, dark theme. On some incoming email, it is white text on white background. I believe this is email that the sender has created on outlook. I have to highlight the text to read their email. Is there a fix for this on my side? Same with any theme I try. Under fonts and colors I went to colors and set Override the colors specified by the content with my selections above to "always" but it changed the Thunderbird menus and made them unusable. Tried "only with high contrast" option with no change.

Thank you.
