when I open a modal sometimes the contents of the modal appear before the actual modal is opened. For example in the code below sometimes when I click on the button the contents appear above the button for half a second or so and after that the dialog is rendered correctly. This happens most often when the project has just been started. The code is:

@page "/"
@using Syncfusion.EJ2.Blazor.Popups

@if (this.IsModalShown)
    <EjsDialog header=@("Test Modal")
        <div asp-validation-summary="All" class="text-danger"></div>

        <div class="form-group row">
            <label for="Name" class="col-2 col-form-label">Name</label>
            <div class="col-4">
                <input for="Title" class="form-control" />

        <div class="form-group row mt-2">
            <label for="Number" class="col-2 col-form-label">Number</label>
            <div class="col-4">
                <input for="Number" class="form-control" />

        <button @onclick=@(() => this.IsModalShown = false)>Close Modal</button>

<button @onclick=@(() => this.IsModalShown = true)>Open Modal</button>

    public bool IsModalShown { get; set; }

Hi Ivan, 
Greetings from Syncfusion support. 
We were able to reproduce your reported scenario, while render Dialog dynamically. Currently we are validating the issue in our end and will get back to you with further details on or before 14th August.

Hi Ivan, 
Good day to you. 
We have validated the reported issue, it occurs due to dialog component takes few seconds to render initially on page load. After, the component renders without delay. Currently, we are working with high priority to overcome this component rendering delay and this fix will be included in the patch release which is expected by the end of August.
