I'm trying to find the face that applies to this tooltip in LSP in rust-mode with rust-analyzer, but I'm not seeing anything when I search on:
- tooltip
- lsp
- popup
- posframe
- lsp-rust-analyze
- faces
- lsp-ui
If there's a general method that works to identify faces you can't put the cursor on, or if someone knows what that annoyingly light background face is, I would love the help.
