bug: After deleting lines in quickfix buffer jumps to remaining entries in quickfix are inconsistent

[chancez]

Neovim version (nvim -v)

NVIM v0.11.4

Operating system/version

MacOS 15.6.1

Describe the bug

If you delete entries from the quickfix window, then try to jump to an entry from the quickfix by pressing enter, the entry you jump to is not the one selected, but the one that was in that position before being deleted.

What is the severity of this bug?

breaking (some functionality is broken)

Steps To Reproduce

1. Open quickfix
2. Delete some entries in the quickfix list.
3. Press enter on a quickfix entry that is in a new location after the previous entries were deleted
4. See that the entry you jumped to is not the one you selected

Expected Behavior

I expect to delete lines in the quickfix window that I don't care about, then be able to jump to the remaining entries.
