I very strongly think that semicolons should be placed outside of bolded text as we have previously systematically done.
We only allow bolded colons because it looks clearer and more consistent in the beginning of statistics, as well as because it would cause enormous amounts of unnecessary work to change it at this point, and that is it, whereas bolded semicolons would cause an ugly inconsistency in our labelling structure, as detailed above, and would also cause enormous amounts of incoherence in our pages until we have spent enormous amounts of wholly unproductive and unnecessary work applying the change.
We simply forgot to mention this in our common editing mistakes page, due to focusing on including more pressing problems at the time.
So, again, I definitely very strongly oppose this suggested change. My apologies.
