Editing Displayed text generates multiple links

I've created a new target development branch, 7.1.x, for this work, since it will require introducing backwards-compatibility-breaking changes. See https://www.drupal.org/project/linkit/releases/7.1.x-dev →

This sounds exactly like the same issue I described in #3534699-14: Refactor plugin for CKEditor5 v45+ → .

use 7.0.7 and MR122 from https://www.drupal.org/project/linkit/issues/3535479 📌 Refactor Linkit plugin for CKEditor5 v45+ Active (hidden branch)

use 7.0.7 and MR122 from https://www.drupal.org/project/linkit/issues/3535479 📌 Refactor Linkit plugin for CKEditor5 v45+ Active (hidden branch)

In my testing today, using that MR does not have any effect or resolving this particular issue. Regardless of whether Editor Advanced Link is being used, the problem described above still happens, triggered by clicking within the link text and editing the link, as shown in the screencast below.

I have opened a new merge request that applies to the new 7.1.x branch and which replays the proposed changes from MR122 from 📌 Refactor Linkit plugin for CKEditor5 v45+ Active , specifically switching to the CKEditor balloon API, replacing previous code that was a workaround. As you'll see, the problem described in that issue is still present with those changes.

I'll keep working on this, but to me, this suggests that the solution may NOT require backwards compatibility-breaking changes. Rather the underlying problem seems to do with how Linkit is find the CKEditor link start and end (i.e., the "selection range" when an existing link is clicked on.
