The error message says "This browser is not supported". Doesn't work with Chrome Mask, so we'd need to dig more.

This is another nicochannel site, as seen in bug 1844503. If we resolve this, it will likely resolve the blockage in the related sites for which our existing intervention is currently broken.

(In reply to Dennis Schubert [:denschub] from comment #1)

The error message says "This browser is not supported". Doesn't work with Chrome Mask, so we'd need to dig more.

For reference, the actual Japanese text shown on the site is:

このブラウザはサポートされていません。

That string appears twice in their source files (from searching devtools debugger for that text). The relevant match for this video is:
https://qlover.jp/assets/VideoDescription-0d8f6b4f.js

If you view that JS file directly, the glyphs are encoded differently for some reason, so find-in-page won't find them. The relevant snippet shown in DevTools (with the encoding of the glyphs that I quoted above) is:

xi = ({
  thumbnailUrl: e
}) => {
  const t = Mi();
  return h(
    'div',
    {
      className: t.container,
      children: [
        i(ft, {
          src: e,
          aspectRatio: ht.SIXTEEN_TO_NINE,
          block: !0
        }),
        i(
          'div',
          {
            className: t.absoluteCenter,
            children: i(
              G,
              {
                variant: 'body1',
                color: 'inherit',
                noWrap: !0,
                className: t.desc,
                children: 'このブラウザはサポートされていません。'
              }
            )
          }
        )
      ]
    }
  )
},
