azure-sdk-for-net: [BUG] SasQueryParameters unable to parse multiple DateTime query parameters from a Uri authenticated with a Sas Token

Describe the bug GetBlobClient is unable to parse my Uri if I have multiple date query parameters. Note that I am using a SAS token generated from an azure storage using version 2017-04-17.

Expected behavior What is the expected behavior? I would expect that the query string would be able to be parsed and if it was invalid I would hit a 403 web request error.

Actual behavior (include Exception or Stack Trace) What is the actual behavior? I hit a Format Exception at SasQueryParameters…ctor(IDictionary`2 values)

See exception detail here:

Exception Type: System.FormatException
Error message: String was not recognized as a valid DateTime. 
at System.DateTimeParse.ParseExact(String s, String format, DateTimeFormatInfo dtfi, DateTimeStyles style, TimeSpan& offset)
at System.DateTimeOffset.ParseExact(String input, String format, IFormatProvider formatProvider, DateTimeStyles styles)
at Azure.Storage.Sas.SasQueryParameters..ctor(IDictionary`2 values)
at Azure.Storage.Blobs.BlobUriBuilder..ctor(Uri uri)
at Azure.Storage.Blobs.BlobContainerClient.GetBlobClient(String blobName)

To Reproduce Steps to reproduce the behavior (include a code snippet, screenshot, or any additional information that might help us reproduce the issue)

I am able to reproduce using Linqpad that while I am able to use the containerService, the blob service fails. I’ve redacted identifying information, but the below code will still error out since we fail before issuing the web request.

void Main()
{
	var baseUrl1 = "https://serviceAccountName.blob.core.windows.net/";
	var queryString1 = "sv=2017-04-17&sp=rl&sr=c&sig={redacted}&se=2020-12-25";
	
	var uri1 = new UriBuilder(baseUrl1)
	{
		Query = queryString1
	}.Uri;

	var serviceClient = new BlobServiceClient(uri1);
	var container = serviceClient.GetBlobContainerClient("aptdata");
	var blobClient = container.GetBlobClient("randomBlob"); // fails here
}

The same information works using the Azure CLI
