📝 Provide detailed reproduction steps (if any)

1. Open the Collaborative Editor in classic mode, with the horizontal line plugin, in Firefox.
2. Click below a horizontal line
3. Drag select upward getting the horizontal line and text above it.

✔️ Expected result

We should be able to drag up toward a horizontal line and select the horizontal line and the text above it, without any errors or buggy movement that takes us to the top of the page.

What is the expected result of the above steps?

❌ Actual result

1. Error is thrown: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-model-selection-range-intersects
2. Buggy movement Editor moves up taking us to the top of the page.

Hi, thanks for the report. I confirm this bug, it's a regression introduced in version 20.0.0.

Bisection shows this commit: 824d731

It seems to be the same issue as in #7892. The same browser, steps and bisection result. I'll close this one for now as a duplicate and let's track it there.
