gnome-wayland: unable to change $PATH at gnome-shell level

I can't change the PATH at gnome-shell level so I can execute programs in my ~/bin or ~/.local/bin folder from my .desktop files. I am able to easily define other variables through ~/.config/environment.d/envvars.conf e.g. TEXMFHOME. The problem is reported elsewhere and most recently on these pages: - https://www.reddit.com/r/archlinux/comments/i2ybvc/cant_change_path_in_environmentd5/ - https://gitlab.gnome.org/GNOME/gdm/-/issues/385 - https://gitlab.gnome.org/GNOME/gdm/-/commit/349e6af855a1c1dbee9af3e5881e00b66482d155 I have changed these files:

~/.bashrc : 
export PATH="$HOME/.local/bin:$PATH"

~/.config/environment.d/envvars.conf:
PATH=$HOME/.local/bin:$PATH
TEXMFHOME=$HOME/.texmf # this variable is available at gnome-shell level

~/.pam_environment
PATH        OVERRIDE=${HOME}/bin:${HOME}/.local/bin:${PATH}

/etc/environment
PATH=/home/farid/.local/bin:$PATH

And at my bash prompt in gnome-terminal, I get:

The TEXMFHOME variable set in ~/.config/environment.d/envvars.conf file is available to Gnome-shell but PATH seems to be overridden by some program. I am not sure if it's related to systemd or Gnome-shell, But in the reddit link I shared above, a person says the problem stems from Gnome-shell. I expect that when I press alt+f2 and type an executable name which is present in ~/.local/bin/ to be executed. I reported the bug to Debian gnome-shell package maintainers as well: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1104035 If I press alt+f2 and execute sh -c 'echo "$PATH" > /tmp/path', then the content of /tmp/path is:

cat /tmp/path
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

If I press alt+f2 and execute sh -c 'echo "$TEXMFHOME" > /tmp/TEXMFHOME', which is defined in ~/.config/environment.d/envvars.conf, then:

cat /tmp/TEXMFHOME
/home/farid/.texmf
