IDE0028 incorrectly triggers for dictionary shallow cloning

[barjonas]

Version Used:
From #error version: Compiler version: '5.5.0-2.26153.17 (68f89b7e2593bb313560a7b612739ae7f8ffd128)'. Language version: 14.0.

Steps to Reproduce:
(Minimal reproduction solution here)

1. Create a new C# console project with a net10.0 target, <LangVersion>Preview</LangVersion>.
2. Add the following code.

using System.Collections.Immutable;
Dictionary<int, ImmutableList<int>> original = new() { { 1, [1, 1] } };
Dictionary<int, ImmutableList<int>> shallowClone = new(original);
Console.WriteLine(shallowClone[1].Count);

Note the analyzer message: IDE0028 Collection initialization can be simplified
3. Apply the Codefix.
Note the buildable result: Dictionary<int, ImmutableList<int>> shallowClone = [with(original)];

Expected Behavior:
No analyzer result OR codefix that produces buildable code.

Actual Behavior:
Analyzer result with invalid codefix.

I'm a bot. Here is a possible related and/or duplicate issue (I may be wrong):

Fixed with #82389

That looks plausible. My only doubt is because it doesn't repro' if the LangVersion is set to 14.0, only if it's set to Preview. As far as I know, Preview should map to 14.0 in my environment, but I don't know of a way to check.
