the HTML tags img, object and embed are not displayed in the title of the second item
the HTML tag object may introduce a strange nesting in the tree structure (see picture : the tree items are at the same level but the 2nd and 3rd seem to be associated)
When a title contains some HTML tags, it may not be properly rendered in the tree view and may impact the tree structure.
