Context help sometimes doesn't show help for methods

As can be seen in the screenshot below, the help content for addWidget is not shown in the context menu. Opening

To reproduce, open the Qt Screenshot example (from Qt 6.5), navigate to screenshot.cpp, and hover over the addWidget method. The same applies to e.g. setWindowTitle, but not to e.g. addStretch in buttonsLayout->addStretch();.

Opening the help side bar with F1 on the same cursor position shows the help successfully – in some cases after selecting the correct topic first, in others like mainLayout->addWidget(optionsGroupBox); even without having to select a topic.
