Really?

Setting an arg to nil _"causes"_ bugs?
And this though nil is a documented
valid value for optional arg PARMS?
Good golly!

And what do you mean by "the user's
tooltip color customizations"?  There's
nothing in that call that makes any use
or mention of anything user-defined.

With such a call no user should expect
anything related to anything they've
customized (unless it's FACE-YOU-WANT
that they've customized - and a face
customization is surely respected).

I wonder, did you actually try what I
suggested?

Anyway I don't see any such sky-falling.
I use such code with no problem.

But then, I don't use the latest and
greatest development of Emacs.

Perhaps some innovative regressions have
been introduced in Emacs 28, or later.
