Call multiple time LoadItemsByCamlQueryAsync return wrong result

[necik11]

PnP.Core 1.7.0

Hello

I'm not sure if this is the problem or if I'm just using this method incorrectly. But i need call method LoadItemsByCamlQueryAsync several times and i in second time i got result what i have got in 1st call.
Description: I have list - lets call listA:

1. I need find folder on those listA.
2. Find folders in folder that I found in the previous query.

So what i am doing its:

// Get List
var listA= context.Web.Lists.GetByTitle("listA",a => a.RootFolder);
context.Execute();

// Find folder 
var folder = FindFolder(listA);
     public static async Task<IEnumerable<IListItem>> FindFolder(IList list, string folderName)
        {
            string viewXml = $@"
<View >
	<Query>
		<Where>
			<Eq>
				<FieldRef Name='Title'/>
				<Value Type='text'>
					<![CDATA[{folderName}]]>
				</Value>
			</Eq>
		</Where>
	</Query>
</View>
";
            await list.LoadItemsByCamlQueryAsync(new CamlQueryOptions()
            {
                ViewXml = viewXml,
                DatesInUtc = true
            });
            return list.Items.AsRequested();
        }
// Find folders with similiar query, but just add this folder 
3.  var folders = FindFoldersInFolder(listA, folder);
 FolderServerRelativeUrl = folder.ServerRelativeUrl

Expectation:
The result will be according to the new spQuery/CamlQuery..,
Result
Previous requested items... its work weird.. seems when query not found any result/items its return previous instead of null or 0...
I will look into this further, any tips would be appreciated

@necik11 : this is expected behavior. When you use a "Load" method we'll load the data into the in memory PnPContext object, for example if you need paging then each page is requested and added so that at the end you've a complete set of rows. If you don't want that behavior the simplest solution is to clear the loaded items before the next invocation of LoadItemsByCamlQuery as is shown in here: https://pnp.github.io/pnpcore/using-the-sdk/listitems-intro.html#using-paging-with-loaditemsbycamlquery

It works!
I would certainly not say that this is expected behavior compared to any version SHP 2010-2019 or CSOM, the items are reloaded when calling LoadItemsByCamlQuery, even you load 0 items... Anyway, clear the loading items works, thanks for fast the answer.
