In a SelectItem with multi select, I cannot select the first element with 'space' key when there a large number of element in the list

[plariviere]

Using the Feature Explorer, the topic "Select List", just modify the JS to add "multiple : true"

When running it, you cannot select the first element with the space key, as is it possible to do with all other item.

I am using this :
Version v12.0p_2021-08-08/Pro Deployment (2021-08-08)

The problem only occurs with large dataset, whith paging, when the data in the SelectItem does not contains all the data set.

Here the code:

isc.DynamicForm.create({
ID:"testForm",
width: 500,
fields : [
{
name: "filteredSelect", title: "Select Item", editorType: "SelectItem",
optionDataSource: "supplyItem",
displayField:"itemName", valueField:"SKU",
pickListPlacement: "fillScreen",
multiple : true,
pickListWidth:300,
pickListProperties: {
showFilterEditor:true
},
pickListFields:[
{name:"SKU"},
{name:"itemName"}
]
}
]
});

Data source:

<DataSource
ID="supplyItem"
serverType="sql"
tableName="supplyItem"
titleField="itemName"
testFileName="/examples/shared/ds/test_data/supplyItem.data.xml"
dbImportFileName="/examples/shared/ds/test_data/supplyItemLarge.data.xml"
