Next/previous page key not working for certain webcomics

[Disclaimer: Probably not an actual bug, more like a cry for help.]

Describe the bug
I use the [[ and ]] bindings a lot when reading web comics, they're an awesome feature! ❤️

However, for this one webcomic, Order of the Stick it doesn't work for me. The buttons for previous/next have both alt text and title "Previous Comic," respectively "Next Comic," and I've tried adding those strings to the Previous/Next patterns but it hasn't help.

To Reproduce
Steps to reproduce the behavior:

1. Go to URL 'https://www.giantitp.com/comics/oots1261.html'
2. Type ]] or [[, the former doesn't do anything, the latter seems to click "News."

Settings I tried:

Previous patterns: prev,previous,back,older,<,‹,←,«,≪,<<,Previous Comic
Next patterns: next,forward,more,newer,>,›,→,»,≫,>>,Next Comic

Browser and Vimium version

   Name  Firefox

Vimium 1.67.1

Start by reproducing the issue at the Order of the Stick URL with the configured [[ and ]] bindings, then trace how Vimium identifies previous and next links using their alt text and title. Done means both bindings activate the comic's corresponding links without selecting the News link, with the behavior verified on the reported page.
