Bug: inline DecoratorNodes are over-eagerly deleted

[sedson]

If an Element terminates with an inline DecortorNode (here using Equation) then deleting the new line below the decorator also deletes the decorator.

Lexical version: v0.21.0+dev.esm

Steps To Reproduce

1. On line 1, insert an equation - make sure there are no text nodes after it.
2. Press backspace from selection offset 0 on the line below.
3. The DecoratorNode will be deleted.

Hi, I was working on this today and noticed that pressing backspace deletes the previous node instead of merging them. Interestingly, in the playground example, it works as expected. I initially thought it might be a bug on my side. Is there something I need to adjust or fix to resolve this?
