Pressing F1 for Qt object help opens the help page for the symbol under text cursor instead of the one being hovered over

Hovering a mouse cursor over a Qt object symbol in a C++ file shows a tooltip prompting to press F1 for the help. However pressing F1 actually opens a help article for the symbol under the text cursor, not the symbol being hovered over, see the attached clip. Notice that in the video the text cursor is placed onto v variable of type QVector<int> and then the mouse cursor is hovered over test variable of type QString. When F1 is pressed it opens help for QList (to which QVector is an alias) instead, not QString.
