FreeBSD 15.0-BETA3 - no iwlwifi0 wifi firmware after install

During the install, I successfully connect to wifi and download 
pkgbase.  After booting into the freshly installed system, no wifi and 
this in /var/log/messages:

required
Oct 30 01:04:29 freeburg kernel: iwlwifi0: check 
git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
Oct 30 01:04:29 freeburg kernel: iwlwifi0: On FreeBSD the firmware 
package can be installed running fwget(8).

During the install the fwget step, it says nothing to download.

My workaround has been to open a shell during the install and 
copy /boot/firmware/iwlwifi-QuZ-a0-hr-b0-77.ucode 
to /mnt/boot/firmware/iwlwifi-QuZ-a0-hr-b0-77.ucode. Only then do I have 
wifi on a fresh install and can run 'fwget', which downloads all the 
other iwlwifi...ucode files.

I figure if I have wifi during install, it should work on fresh boot, as 
my /etc/wpa_supplicant.conf is setup correctly by the installer.
