Description

I have an Older Application working with rollup now I need to run some parts without bundler and tried to use the lit-all.min.js the full application is working fine with rollup and does not use decorators so it is browser compatible. The App relies heavily on Mixins and every time I try to use any Mixin it lit-all.min.js gives this error just switching the Mixins.

Reproduction

I could not get the Playground to replicate this behavior.

Workaround

Don't use Mixins

Is this a regression?

Yes. This used to work, but now it doesn't.

Affected versions

Failing in CDN version, Working in 3.0.2 npm

Browser/OS/Node environment

For the Current log, I used Firefox 127.0.2. But Chromium has a similar problem with this._$AL.has() is not a function.

Start with the CDN build in media/plugins/symcon/auth/js/libs/lit-all.js and the mixin files named in the stack trace, especially user-pool-mixin.js, show-error-mixin.js, and determine-language-mixin.js. Compare the failing CDN version with the working 3.0.2 npm version and inspect licenses-page.js as the entry point. Done means reproducing the regression or documenting why the CDN build fails when mixins are used.
