Gradient Thames

Hello! Can you fix the display of embed messages from webhooks when using a dark or light theme with a gradient? Embed messages don't change; they stand out significantly from the color scheme. 

Edit; I also noticed after I wrote the post that settings, pinned messages, list with participants, preview of channels, events, threads and mail can also be corrected, I’m sure that this is not the whole list in which the theme is not used
