RadzenSplitterPane visibility

Radzen.Blazor Components
1

Hello! After setting "Visible" parameter to "false" and restoring it to "true" for the left Splitter Pane, the splitter line doesn't show up. What could be the problem? Thank you.

                                <RadzenSplitterPane Size="20.3em" Collapsible="true" Visible=@(!tab.Settings.HideStructurePanel)>
                                    <div class="h-100 w-100" style="margin-left: 1px;">
                                        <TabStructureView DataContext=@tab.Structure/>
                                    </div>                                      
                                </RadzenSplitterPane>                                   
                                <RadzenSplitterPane Collapsible="false">
                                    <div class="h-100 w-100" style="margin-left: 1px;">
                                        <InstrumentTabs DataContext=@tab/>
                                    </div>
                                </RadzenSplitterPane>
                                
                            </RadzenSplitter>
