Hello again 👋
This is a bit of an edge case but when using the plugin with (setq flycheck-overlay-show-at-eol t), it won't display the flycheck warning on an empty line. Using this on a ruby project where I get warnings on unnecessary empty lines, I can see the warning in the list of flycheck-errors but the overlay is missing, I assume because the line is empty. It does not happen when flycheck-overlay-show-at-eol is nil.
Example with flycheck-overlay-show-at-eol nil
