[BUG] BlobClient cannot read blobs with # characters in name

[jkdmyrs]

Library name and version

Azure.Storage.Blobs 12.19.1

Describe the bug

The BlobClient incorrectly truncates blob file names if the name contains a # character.

Expected behavior

The following code should output:

example#test.json
example.json

Code:

using Azure.Identity;
using Azure.Storage.Blobs;

BlobClient blobClient1 = new(new Uri("https://example.blob.core.windows.net/example/exmple#test.json"), new DefaultAzureCredential());
Console.WriteLine(blobClient1.Name);

BlobClient blobClient2 = new(new Uri("https://example.blob.core.windows.net/example/exmple.json"), new DefaultAzureCredential());
Console.WriteLine(blobClient2.Name);

Actual behavior

The code outputs:
example
example.json

example#test.json is truncated at the # character.

Reproduction Steps

• create a .net 8 console app
• install Azure.Storage.Blobs (and Azure.Identity)
• run this code:

using Azure.Identity;
using Azure.Storage.Blobs;

BlobClient blobClient1 = new(new Uri("https://example.blob.core.windows.net/example/example#test.json"), new DefaultAzureCredential());
Console.WriteLine(blobClient1.Name);

BlobClient blobClient2 = new(new Uri("https://example.blob.core.windows.net/example/example.json"), new DefaultAzureCredential());
Console.WriteLine(blobClient2.Name);

Environment

No response

Seems like this was fixed previously... is this a regression?
