Eldoc in echo area will only show a single line of text, even if eldoc-echo-area-use-multiline-p is t.

[WeissP]

When I call eldoc on a variable in rust, it shows following documentation in the buffer:

// size = 8, align = 0x8
let next_v: u64

But when the documentation is shown in echo area (e.g., via commands defined in eldoc-message-commands), only the first line is displayed. How can I make it display all lines?

the relevant config is:

(setq eldoc-documentation-strategy 'eldoc-documentation-compose)
(setq
 semantic-idle-truncate-long-summaries nil
 eldoc-echo-area-use-multiline-p t
 max-mini-window-height 0.5)
