Can you reproduce any of these problems without the
`default-frame-alist' setting?  In either case, please do the

   frame_size_history = list1 (make_fixnum (100));

assignment and tell me what calling `frame--size-history' gives after
the initial frame has appeared.  After that do

(setq frame-size-history '(100))

run C-x 5 2 and again post what `frame--size-history' returns.

Again, I'd need to know what `frame--size-history' tells about this.  Is
this behavior new or did it already occur in Emacs 27?
