Diagnosis

The function cider--help-echo misunderstands the variable help-at-pt-display-when-idle. In the customize buffer, that variable can be "Never", "Always", "In certain situations". nil is not an option. But the cider--help-echo function checks (not help-at-pt-display-when-idle) to see if help at point is enabled (because it doesn't want to do mouse-based and point-based at the same time, which makes sense.

Adding (setq help-at-pt-display-when-idle nil) to my config works around this issue.

The fix should probably check to see if the value is "never" or nil.
