It seems that, after encountering triple left brackets in wikitext ([[[) within a template, DynamicPageList3 gives up scanning the remainder of the template-parameter values and throws up a blank when trying to retrieve them. This is clearly evident in the recent-post section of my "FTA" ("From the Author") home page at press time, where everything is set up correctly. Of the five displayed, three have their original dates and keyword tags intact; the other two do not.

Across the entire FTA archives at Miraheze so far,[1] three entries are affected: "Happy New Year, folks!", "Going across the pond", "...and back to the anthros". They utilised the "{{!(}}" tag, which produces left brackets ([) before wikilinks. (At least till today, when I replaced the instance in the "Anthros" edition with HTML equivalent [ to see if DPL3 would recognise it; still didn't work.)

If nothing else, this is clearly a long-undetected upstream bug that never even got brought up in the old FollowTheScore documentation or anywhere else. Either we'll see what @Universal_Omega can do about it, or I'll try another workaround.

Another DPL issue as of late: openreferences=(true|yes) not recognised by imagecontainer= (T9056).
