toc-title attribute behaves wrong

[pjanx]

~This should do:~

:toc-title: pass:[<h2>Hello!</h2>]

~what this does now:~

:toc-title: <h2>Hello!</h2>

~which should be HTML-quoted.~

@pjanx could you elaborate, please? I don't understand what the problem is 😬

I'll try to replicate it again, it seems like there is something else at play.

Okay, this is apparently about my use of -a, and asciidoctor doesn't parse it either.
