bug#46025: 28.0.50; warning suppression buttons truncate warnings

The warning suppression buttons introduced in 66d01012ba61a364fe92cdc1728bfa135a90626a truncate warning messages. I have offered a trivial patch in the past to have an option to disable these buttons:

https://lists.gnu.org/archive/html/bug-gnu-emacs/2020-09/msg01405.html

Lars did not see it as a valid use case. His argument (summarized):

since you get the warnings so seldom, it makes sense
to have the very few you see come with ready-made ways of making them go
away, and then you're back to no warnings again.

Initially I thought the idea of the buttons was useful, but after thinking on it more I agree with the case against these buttons Jonas Bernoulli made here:

https://lists.gnu.org/archive/html/emacs-devel/2020-11/msg00768.html

I would add to that, the fact that the buttons truncate the warning messages makes it impossible for a user to make an informed decision on whether or not they should be suppressing the warning. The truncated messages are equally useless to me as a developer. Here's an image someone sent me of the warnings on their system:

While I politely encouraged them to send text in the future for such output,
here's what I would've received:

Warning (comp): Debugger entered--Lisp error: (native-compiler-error-empty-byte "/root/.emacs.d/straight/build/straight/straight-au..." "/root/.emacs.d/straight/build/straight/straight-au...\
") Disable showing Disable logging
Warning (comp): Debugger entered--Lisp error: (native-compiler-error-empty-byte "/root/.emacs.d/straight/build/bind-key/bind-key-au..." "/root/.emacs.d/straight/build/bind-key/bind-key-au...\
") Disable showing Disable logging
Warning (comp): Debugger entered--Lisp error: (native-compiler-error-empty-byte "/root/.emacs.d/straight/build/use-package/use-pack..." "/root/.emacs.d/straight/build/use-package/use-pack...\
") Disable showing Disable logging

It's only by luck I can see enough of the file path to know which files are throwing the errors.

Is there a way to work around this (absent my patch)?
