At https://en.wikipedia.org/w/index.php?title=List_of_American_Dad!_characters&curid=2082680&diff=564675517&oldid=564302759 a user added a link using wikitext. The VisualEditor added <nowiki> tags around it (correct according to apparent design, incorrect according to desired behaviour).
However, it also added <nowiki> tags around every other bit of pre-existing markup in the paragraph. This is incorrect according to my understanding of the design because even if they did want to include a literal string surrounded by square brackets they did not want to alter the existing markup.
Bug 5069 comment 5 suggests to me that this isn't that bug but a different one, but not what number that other bug is.
