ReferenceError: CKEditor5 is not defined

Description

We've a client using Safari 15 hitting an issue where Ckeditor doesn't run in Safari 15, looks to be a JS error "ReferenceError: CKEditor5 is not defined".

Can this be fixed? It's an old browser but does fall in the support range.

Thanks for reaching out! While it's true Craft's CP itself supports Safari 15, CKEditor (and therefore this plugin) only supports the latest stable version.

It looks like the culprit of this issue was CKEditor updating their typescript target to es2022 in v42+. We updated our dependencies to v44 in 3.11 so we don't fall too far behind them.

Unfortunately, if you need to support Safari 15 the easiest way would be to stay on 3.10. If you're feeling ambitious, it should be possible to recomplile CKEditor v42+ with the old target but that might be an uphill battle.

I'm sorry I don't have better news for you. I'm going to close this out, but if you have any other questions, let us know.
