Link in column "Code" of Error List does nothing if Help Viewer is used

[KernelLeak]

I was wondering why clicking on no-constant-condition in the Error List did nothing at all when clicking on, say, CS1002 ("; expected") opened up the Help Viewer with a description.

It started working once I changed Help > Set Help Preference from Launch in Help Viewer to Launch in Browser, but this is absolutely not obvious.

Maybe Web Analyzer could warn the user about that setting, or maybe the link can be changed so that Help Viewer brings up the web page instead, like it does for other documentation that's not installed locally?
