The site seems to have been fixed. The source code now looks like:

let c=r?MangaScroll5column:RankingGrid,m={オリジナル:n,"新人・読切":e,総合:a},d={};

Notice that "新人・読切" is now enclosed in quotes.

Also I'm confused why this a regression from bug 1927706, because bug 1927706 should have actually allowed to run the original source without quotes.

Evaluating ({オリジナル:0,新人・読切:0,総合:0}) in current release reports Uncaught SyntaxError: illegal character U+30FB, whereas with bug 1927706 applied, that code snippet runs successfully. That's because before the update to ICU 76 we were still using Unicode 15, but ICU 76 updated to Unicode 16 and U+30FB (KATAKANA MIDDLE DOT) was added to ID_Continue in Unicode 15.1.

Confirmed the bug was fixed. I can no longer reproduce the ssue on 128esr, 132.0 and 133.
