In HTML output, for lists that have an -indent argument, just use

a uniform indentation in CSS adapted to the viewport width and
ignore the value of the argument taken from mdoc(7).  While
author-specified widths somewhat work as a micro-optimization in
terminal and typeset output, they are nothing but harmful in HTML
style= attributes because they break responsive design, whereas
using a reasonable default indent almost never results in ugly
output.  Admittedly, the author-specified width might occasionally
look even better, but only slightly so, and only for some viewport
sizes.
Based on guidance provided by John Gardner.
