I find myself accidentally clicking the mode line when trying to focus a buffer with the mouse. This causes the buffer to change. I don't want that behavior. I want nothing to happen.
The culprit is this guy here, the part of the mode line that says the buffer's name (e.g. *shell*):
How can I disable it's behavior when it clicked?
I am told it is <down-mouse-1> by C-h k. However, this corresponds to mouse-drag-mode-line which resizes. This is not the behavior I observe. I cannot locate the appropriate key to override.

C-h kis not so useful.C-h kand clicking on the buffer name in the mode-line, I get a*Help*screen with two key sequences described: one is themouse-drag-mode-linefromglobal-mapas above; the other ismode-line-previous-bufferwhich also identifies themode-line-buffer-identification-keymapas described in @lawlist's answer. I'm on GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.13, cairo version 1.16.0).
