Hover should separate multiple summaries

[DoctorKrolic]

Version used: VS 2022 v17.4 Preview 3

To reproduce:

1. Create blazor server app
2. Go to Counter.razor
3. Add this code: <input @bind-value="currentCount" />
4. Hover over input and bind-value

Expected behavior: Multiple summaries are separated with a line

Actual behavior: The are just stacked on top of each other without any separation:

Additional context: Here is how it looks with legacy editor: The coloring is not great at all and the separation line is barely visible, but summaries are a lot easier to destinguish at least because of vertical space between them. The new razor editor should implement the same thing, but with improved coloring of the separation line to be even clearer about it
