I don't have the answer to your question, but I noticed that the "code" HTML tags disappear if you get rid of the empty parentheses in your POD: 
BackupTRM As Boolean

Searching through the docs, here is the closest thing I see, from perlpodspec (emphasis mine):
At time of writing, L<name> values are of two types: either the name of a Pod page like L<Foo::Bar> (which might be a real Perl module or program in an @INC / PATH directory, or a .pod file in those places); or the name of a Unix man page, like L<crontab(5)> . In theory, L<chmod> in ambiguous between a Pod page called "chmod", or the Unix man page "chmod" (in whatever man-section). However, the presence of a string in parens, as in "crontab(5)", is sufficient to signal that what is being discussed is not a Pod page, and so is presumably a Unix man page. The distinction is of no importance to many Pod processors, but some processors that render to hypertext formats may need to distinguish them in order to know how to render a given L<foo> code.
Looking through the source code of Pod::Html, I see this comment: 
    # has parenthesis so should have been a C<> ref
    ## try for a pagename (perlXXX(1))?
