https://secure.wikimedia.org/wikipedia/test/wiki/Thread:Talk:Main_Page/test/test/reply_(3) I entered the text as: <big>big text</big> <small>small text</small> Those should show up on separate lines. '''bold text''' ''italic text'' those, too. but the "big text" and "small text" lines were concatenated onto one line, as were the "bold text" and "italic text" lines.
A single newline in input text terminates a line, but doesn't terminate a paragraph in MediaWiki's wiki text format (and never has), so changing this could be a compatibility issue and cause pages to render incorrectly. Various sequences with templates, tables etc will also be assuming that the linebreak is ok as whitespace and might be modified unpleasantly by just inserting a <br> into output there, so not sure how trivial it would be to do. You can insert an explicit <br> in your input to force a visible line break within a paragraph, though. The <poem> extension tag can also be used to insert line breaks at source newline boundaries within a paragraph.
(This is a general markup issue dating back to UseModWiki, nothing specific about LiquidThreads.)
Got it. Closing this up since I was operating out of ignorance of the desired behavior.
