I see.  Interesting.  I also verified groff 1.18.1 with -z -ww
-mandoc works fine for the sequence above.

But, I am afraid you will see "warning: missing closing delimiter"
if you have:
	.Bl -tag -width ".Em cyl , sector No and Em head"
instead of:
	.Bl -tag

As I did not have a chance to reinstall a recent -current, I installed
groff 1.19 and got the same warning when I format fdisk(8).

Can you format fdisk(8) without warning using groff 1.19?
