This is a change in behavior from Emacs 27 due to this change:

    Add toolbar for help-mode

Prior to this change, clicking the X icon in the tool bar when *Help* is
the current buffer does kill the buffer, but since the change it just
buries the buffer.  This change should be called out in NEWS.

Emacs does give indirect notification of this difference between
clicking the X icon when *Help* is the current buffer and when a buffer
such as *scratch* is current: if you hover the mouse pointer over the
icon when *scratch* is current, you get a tooltip saying "Discard (kill)
current buffer", while with *Help* current the tooltip says "Quit help
(q)".  And if you type `C-h k' with *Help* current and then click the X
icon, the *Help* buffer now says "<tool-bar> <quit> runs the command
quit-window [...]" and further down explains how it is in fact possible
to kill the *Help* buffer from the tool bar: type a prefix argument
(C-u) and then click the icon.
