I figured out my problem.
I was using [+ my_sub() +] instead of [- my_sub() -]
where my_sub was defined using [$ sub my_sub $] ... [$ endsub $]

It wasn't obvious to me (nor do i see it documented anywhere),
but calling such subs with [+ +] seems to wreak havoc.

Using [+ my_sub () +] will just, in addition to what the sub is already
outputing, output the return value of the sub, which might be in your
case some html.

So just to confirm my understanding:

if a sub uses only [- -] and returns an html value, then it can and
should be called with [+ +].
alternatively, the sub can use [+ +] internally and the caller can
use [- -] to call it.
just don't mix the two.

Yes.

In addition, if you have no output inside the sub, then just use a
normal Perl sub. If you have output in the sub, you should use [$ sub
$]. The benefit of using [$ sub $] and [+ +] inside, is that you get
only the from perl outputed data escaped, while when outputing a large
block of html, you have to care by your own about proper escaping
