/etc/profile.d/snapd.sh is overwriting PATH and XDG_DATA_DIRS

snapd is creating a file /etc/profile.d/snapd.sh which is overwriting the PATH and XDG_DATA_DIRS variables:
    PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/sbin:/builddir/.local/bin:/builddir/bin:/snap/bin
    if [ -z "" ]; then
        XDG_DATA_DIRS=/usr/local/share/:/usr/share/:/var/lib/snapd/desktop
    else
        XDG_DATA_DIRS="":/var/lib/snapd/desktop
   fi
   export XDG_DATA_DIRS

This is on Fedora 24 GNOME version. Snapd was installed using the Copr repo.

What was expected:

PATH variable with its default value appended with /snap/bin.
XDG_DATA_DIRS variable with its default value appended with /var/lib/snapd/desktop.

What happened instead:

The default value of PATH variable is overwritten.
The default value of XDG_DATA_DIRS is overwritten.

A simple fix which I used:
    PATH=$PATH:/snap/bin
    XDG_DATA_DIRS=$XDG_DATA_DIRS:/var/lib/snapd/desktop
