String interpolation errors when concatenating multiple string

[ceccomil]

Using Preview 7, It was working on Preview 6, I got this weird behaviour.

Considering this simple console app:

using System;

//NET6.0 Preview 7

var myValue1 = "|someValue|";
var myResult = $"I want the value here: {myValue1}"; //this is fine 
Console.WriteLine(myResult);
Console.WriteLine();


myResult = $"I want the value here: {myValue1};" +
    $"Another String using {myValue1} in the middle";
Console.WriteLine(myResult);
Console.WriteLine();

This is the result I'm getting (see also picture below):

I want the value here: |someValue|

;|someValue|I want the value here:  in the middle|someValue|Another String using

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

It might have been fixed by #55494 in 17.0p4, but I am not 100% sure so I would prefer someone from the Roslyn Team to confirm

Yes, this is a dup of #55461.
