HTML tags appear in page titles when formatstringstriptags is disabled

With formatstringstriptags disabled Go to Site Admin > Appearance > HTML Settings and make sure "Remove HTML tags from all activity names" is checked Create a course Add an activity (any will do but lets say a quiz) Give activity the name "<span style="font-size:2em;">My Quiz</span>" and save View the activity Result: The activity will be created. When viewed the activity on the page the title will exclude the tags e.g. it will be "My Quiz". The font size will be normal and the browser title won't include any tags. With formatstringstriptags enabled Go to Site Admin > Appearance > HTML Settings and make sure "Remove HTML tags from all activity names" is not checked Create a course Add an activity (any will do but lets say a quiz) Give activity the name "<span style="font-size:2em;">My Quiz</span>" and save View the activity Result: The activity will be created. The browser title bar will still exclude the tags e.g. it will be "My Quiz". The activity name will now include the tags, so the activity name on the page will be in a large font. No HTML tags in the activity name If the activity name doesn't include HTML tags then the result is the same with formatstringstriptags on or off - the activity name should be displayed unchanged in the title.
