My current host: FreeBSD 13.0-CURRENT r340319 and the problem is still present. As I recall, I first encountered this problem when FreeBSD-CURRENT (12) moved to the ALPHA-1 state. At least a month before the ALPHA-1, everything worked fine. At this time, the bootloader was changed to work with lua (and the distinguishing feature is that during this transition the boot menu lost color in the UEFI GOP mode). So, the first thing I thought was that it was related to the lua based menu. Now we know that it is not. However, the root of the problem lies at this time.
