Syntax Highlighting only work when I refresh my page, not when I navigate to it.

[VictorioBerra]

I assume this is probably an easy one and I am doing something wrong as I am not a Blazor expert.

I have a page that needs to check the query string, and then call my database for the data for the editor (diff editor specifically).

I followed the examples and first I tried using OnDidInit="EditorOnDidInit"

I have tried putting all of my code in protected override async Task OnAfterRenderAsync(bool firstRender)

I have tried putting all of my code in protected override async Task OnInitializedAsync()

I have tried calling StateHasChanged() after all of the above.

Current Code:

@page "/diff"
@using System.Web
@using Microsoft.Data.SqlClient
@inject NavigationManager NavManager
@inject AppOptions appOptions
@inject IJSRuntime jsRuntime
@rendermode InteractiveServer

<style>
    .monaco-editor-container {
        height: 600px;
    }
</style>

<h3>Diff template #@templateId</h3>

@if (loading)
{
    <FluentProgressRing></FluentProgressRing>
}

@if(sourceEnvironmentEditorTemplate is not null && destinationEnvironmentEditorTemplate is not null)
{
    <table class="table">
        <thead>
            <tr>
                <th>Field</th>
                <th>@sourceEnvironment</th>
                <th>@destinationEnvironment</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <th>Description</th>
                <td>@sourceEnvironmentEditorTemplate.Description</td>
                <td>@destinationEnvironmentEditorTemplate.Description</td>
            </tr>
            <!-- More redacted for brevity -->
        </tbody>
    </table>

        };

I am navigating here from a button click like so:

   // My other interactive server page...

    private void ButtonClick(string x, string y)
    {
        NavManager
        .NavigateTo($"/Diff?sourceEnvironment={z}&templateId={x}&destinationEnvironment={y}");
    }

Possibly/probably related to #126 @serdarciplak any advice?
