Hi, I came across some reports that WP_PLUGIN_URL was broken sometimes giving a non SSL url from SSL pages, but those reports seem to be several years old.
They suggest using plugins_url() instead of the constant.
Is that still the case or has it been fixed?

seems to say it is fixed 11 months ago, is it really or are there still issues in some contexts?
