how to show an error in a modal window when encountering an error

Using Blazor and Blazorstrap, typically when the server disconnects, an "Error" message is displayed. However, with the BsModal from Blazorstrap, it appears in the background layer, making it unresponsive. How can this be fixed? Is it possible to close the BsModal in such situations?

_Host.cshtml

<div id="components-reconnect-modal" class="my-reconnect-modal components-reconnect-hide">
    <div class="show">
        <p>
            attempting to connect to server
        </p>
        <a href="" class="reload">Reload</a>
    </div>
    <div class="failed">
        <p>
            failing to connect
        </p>
        <a href="" class="reload">Reload</a>
    </div>
    <div class="rejected">
        <p>
            refused
        </p>
        <a href="" class="reload">Reload</a>
    </div>
    </div>
    <app>
        <component type="typeof(App)" render-mode="ServerPrerendered" />
    </app>
    <div id="blazor-error-ui">
        <environment include="Staging,Production">
            An error has occurred. This application may no longer respond until reloaded.
        </environment>
        <environment include="Development">
            An unhandled exception has occurred. See browser dev tools for details.
        </environment>
        <a href="" class="reload">Reload</a>
        <a class="dismiss">🗙</a>
    </div>

Normally error display

Error displayed under the modal window layer

Answer â„–1

Here are two different strategies to consider:

First, simply rearrange

<div id="blazor-error-ui">
</div>

and place it

<div id="components-reconnect-modal"...>
</div>

Alternatively, assign unique z-index values to each of these layers (divs) in their styles or classes:

<div id="blazor-error-ui" style="z-index:9999" >

or, within the CSS file under the rule #blazor-error-ui { ....; z-index: 9999 }

and, if necessary, assign a lower z-index value to the "components-reconnect-modal"
