Unconstrained monospace delimiters not working correctly

[TobiasZawada]

Expected behavior

The following text contains an unconstrained monospace-formatting pair. The two opening and the two closing backquotes should be fontified with adoc-meta-hide-face.

``man``page

Actual behavior

The first backquote is fontified with adoc-meta-hide-face, the second is fontified with (adoc-typewriter-face adoc-verbatim-face). The first closing backquote is fontified with adoc-meta-hide-face the second closing backquote is fontified as normal text.

Steps to reproduce the problem

Start emacs -Q, load adoc-mode.el, find new file test.adoc and paste above text into the file buffer.
Then you should observe the actual behavior.
