ButtonType.Link - href not rendered when there's a custom attribute and an HTTP call

[kbaley]

Describe the bug

When the following is rendered, the <a> tag doesn't have an href attribute:

@page "/counter"
@using BlazorBootstrap
@inject HttpClient HttpClient;

<Button Type="@ButtonType.Link" To="/my-route" moo="moo">Moo</Button>

@code {
    protected override async Task OnInitializedAsync()
    {
        await HttpClient.GetStringAsync("https://jsonplaceholder.typicode.com/posts/1");
    }
}

If I remove the custom moo attribute or comment out the HttpClient call in OnInitializedAsync, then the button/link is rendered properly.

To Reproduce Steps to reproduce the behavior:

1. Add a Button with Type=ButtonType.Link and a URL for To and a custom HTML attribute
2. Add an HttpClient call in OnInitializedAsync()
3. Render the page

Expected behavior Clicking the button should redirect to the URL specified in the To property.
