iPad & Tahoe skin:hang up after SelectItem clicked

[GK]

GWT 2.8.2/LicenseType=Pro/SmartGWT6.1p Built2018/03/03, iPad, Chrome

Use Tahoe skin, and after click SelectItem on iPad/iPhone, I can not click any widgets.
LGPL Edition works well.

------------------------------
DynamicForm form = new DynamicForm();
DateItem dateItem = new DateItem();
dateItem.setTitle( "Date" );

LinkedHashMap<String, String> valueMap = new LinkedHashMap<String, String>();
valueMap.put( "US", "<b>United States</b>" );
valueMap.put( "CH", "China" );
valueMap.put( "JA", "<b>Japan</b>" );

SelectItem selectItem = new SelectItem();
selectItem.setTitle( "Select" );
selectItem.setValueMap( valueMap );

TextItem textItem = new TextItem();
textItem.setTitle( "Text" );

ButtonItem button = new ButtonItem();
button.setTitle( "Button" );
button.addClickHandler( event-> {
SC.say( "OK" );
} );

form.setFields( dateItem, selectItem, textItem, button );

We are not reproducing such a problem in the online SmartGWT EE Showcase, for example, in the "Various Controls" sample which features several select items, nor in other samples that have select items. Can you reproduce the problem there?
