E-Mail list mode => Response's from Forum to Thunderbird E-Mail client => embeed Text not readable => White Box with Text, but not readable

Hello,
I using the E-Mail Client Software Application ThunderBird - it is a Free Software Product for wide Range of Operating System’s (Windows, MacOS, …).
When I recieve Text from this Forum, and I open the Text in Thunderbird, they are two Modes:

  • the normal Mode: Text is readable,
  • the embeed Text Mode: the Text content is embeed a white Text Container, and as such,
    it is a disadvantage (or I don’t know, how to set the Options so, that they Support the dark
    Mode for E-Mail Articles.
    The Forum itself can be read in normal Mode, and all is readable (at the current Time, I
    use the dark Mode within this Forum

Can you check against this with Feedback from other User’s ?
Thank’s for reading
Jens
