spacemacs-jump-handlers not set properly for C++ on emacs 27

[emacs18]

I would like to report that "g d" does not work for c++ buffers on first loading a c++ file, but works when the buffer is reloaded. This problem occurs only on emacs 27, but not on emacs 26. I build my own emacs using latest source code from git repository on Red Hat 6.6. I also use latest develop branch of spacemacs.

I have lsp-mode enabled using ccls backend. When I start emacs and open a c++ file, then "g d" does not work at first, because spacemacs-jump-handlers value is this:

(spacemacs/helm-gtags-maybe-dwim evil-goto-definition dumb-jump-go)

If I now hit "SPC b R" to revert the buffer to force re-initializing the buffer, then "g d" starts working which is not surprising since spacemacs-jump-handlers value is now this:

((lsp-ui-peek-find-definitions :async t)
 spacemacs/helm-gtags-maybe-dwim evil-goto-definition dumb-jump-go)

Note that the value of spacemacs-jump-handlers-c++-mode is

((lsp-ui-peek-find-definitions :async t)
 spacemacs/helm-gtags-maybe-dwim)

Why does it require re-loading a c++ file in order initialize spacemacs-jump-handlers correctly on emacs 27? Once it is set correctly, then subsequent c++ files loaded work fine without requiring reloading.

I noticed this issue still exists for spacemacs 27.2. Any way to fix it? @emacs18

BTW: I am on the develop branch, MacOs system. @github-actions

I do not see this problem anymore on emacs 27.2, ubuntu 20.04, and latest spacemacs, i.e., g d command works first time. Following shows my startup file which differs from default with regard to C++ and lsp.
