What were you doing?

1. Install the hebrew locale version of Nightly
2. On any page, open the devtools (doesn't matter which one)
3. Go to Accessibility tab
4. On the description, see the "Learn more" link (in hebrew: מידע נוסף)

What happened?

The text is not linked.

What should have happened?

It should be.

Anything else we should know?

Both relevant strings in Pontoon are translated:
https://pontoon.mozilla.org/he/firefox/all-resources/?string=189732
https://pontoon.mozilla.org/he/firefox/all-resources/?string=189742

:flod, is there anything pontoon-related issue with that that I may have missed?

It looks correct to me
https://pontoon.mozilla.org/he/firefox/devtools/client/accessibility.properties/?search=accessibility.description.general.p1&string=189732

I wonder if the problem is in this code
https://searchfox.org/mozilla-central/source/devtools/client/accessibility/components/LearnMoreLink.js

So, what the code does is

1. Replace %S with the "Learn more" text, resulting in

חוקר הנגישות מאפשר לך לבחון את עץ הנגישות של העמוד הנוכחי, בו משתמשים קוראי מסך ושלל טכנולוגיות מסייעות נוספות. מידע נוסף

2. Use a regular expression to replace מידע נוסף.

I don't think \b is a valid choice for non ASCII text

const messageString = 'מסייעות נוספות. מידע נוסף';
const learnMoreString = 'מידע נוסף';
const re = new RegExp(`(\\b${learnMoreString}\\b)`);
let contents = messageString.split(re);
print(contents[1]);

/*
undefined
