bug#53062: 29.0.50; Inserting charger causes keyboard event <dead-circumflex>

[Theodor Thornhill via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

So, I noticed that everytime I insert my charger the echo area echos
"dead-circumflex-".  Obviously I:

(global-set-key (kbd "<dead-circumflex>") 'save-buffers-kill-emacs)

Now everytime I insert my laptop charger emacs is killed.

Is this expected?  I pulled and built emacs from source just now, and
still get that behavior.

Happy new year,
Theodor Thornhill
