I thought it was a good idea to edit the title of the following question: What is the source of this E̶r̶d̶ő̶s̶ quote?
I wanted to strike through (
like this) the name Erdős, but apparently the html tag does not work for titles
Is this a bug or is this restriction intended? Is there a reason why we should not allow strike through of characters? The question What HTML tags are allowed on Stack Exchange sites? explains what subset of html is allowed in questions; what is the subset that is allowed for titles?
