Hi Mark,
Linkit and other modules with plugins for CKEditor5 are having lots of issues with v45 since it had some big changes.
I was testing linkit on OOTB 10.5 and 11.2 and it had some inconsistent behaviour (loosing attributes, not working with other CKEditor plugins) (Also CKEditor5 v45 have updated how "Displayed text" is being updated).

I've started refactoring of the plugin - let me know your feedback.

cheers,
Janna

Hi Jannahka,

Thanks so much for digging into the CKEditor v45 changes. These are certainly a priority. I'd begun some similar work, refactoring tests and refactoring for the problematic behavior in 🐛 Cannot replace 'Displayed text' of existing links Active . Ideally, I'd like to make only the minimal changes necessary and see if it is possible to retain backward compatibility with previous versions of CKEditor so that we don't have to change the core_version_requirement in a new release.

To that end, it will be important to document exactly what is known to be breaking, with steps to reproduce, so that we can ensure that we're only changing what is necessary and not breaking other things.
