Questions: How the data validation works for Blogifier

[LinQiaoPorco]

Does the floating data validation message come from standard ASP.NET Core Blazor data binding and validation function? It seems different with the standard red text validation message:

I tried to switch Blogifier from local sign-in to OpenID Connect sign-in, but I found the profileview.razor in Blogifier.Admin reported that the data validation failed, because the OnInvalidSubmit was triggered:

<EditForm Model="@Author" OnValidSubmit="SaveProfile" OnInvalidSubmit="ShowErrorSummary"> and protected void ShowErrorSummary() { displayValidationErrorMessages = true; }

but no error message printed out by <ValidationSummary /> as: `@if (displayValidationErrorMessages) {

Validation Messages:

}`

I believe popup in your screenshot coming from standard HTML control validation driven by input type set to "email"

<input class="form-control" type="email" @bind="Author.Email" />
