Sometimes Copilot eats part of the prompt. And I think I understand why.
For example, if you write "A whimsical dark marvel (and other) illustration depicting A humanoid muscular capybara" then Copilot will pack you the following prompt as a result: "A humanoid muscular capybara".
This does not mean that the first part is not used.
It's just that in the end, your prompt may not be who he claims to be
