Suspicious use of the "!" operator inside the "instanceof" operator

[j4y]

I'm upgrading an application to Angular 18 and the new build system throws a warning:

▲ [WARNING] Suspicious use of the "!" operator inside the "instanceof" operator [suspicious-boolean-not]

    src/my-application/app/vendor/zing-touch/zingtouch.min.js:893:14:
      893 │           if (!t instanceof u) throw new Error("Parameter gesture...
          │               ~~
          ╵               (!t)

  The code "!x instanceof y" is parsed as "(!x) instanceof y". You need to insert parentheses to get "!(x instanceof y)" instead.

It doesn't look like a big deal, but the fix looks pretty simple.

This is with the latest zingtouch.min.js from the dist directory.
