Blazor Server (.NET 10 / InteractiveServer): initial Value shows up ~10s late (editor renders immediately, content delayed)

[hrosteck]

When using MudExRichTextEdit in Blazor Server with global InteractiveServer render mode, the editor UI (toolbar + container) renders immediately, but the initial HTML value doesn’t appear until ~10 seconds later.

This happens even though the bound value is already present on the server side.

Im using the latest Version from MudExRichTextEdit.
I have uploaded a short GIF to illustrate the problem:

Here is some example code
<MudExRichTextEdit Value="Example text" ValueChanged="OnSalesTextOverrideChanged" Tools="_tools" Modules="_modules" Height="235" Immediate="true" Placeholder="" Class="rte" />

@code{ private QuillTool[] _tools = QuillPresets.Minimal.Tools; private IQuillModule[] _modules = QuillPresets.Minimal.Modules; }

I was able to resolve the problem by editing MudExRichTextEdit.razor.cs and moving line number 355 (_initializationTcs.TrySetResult(true)) to line 351.

It seems to be getting deadlocked and always timing out because the ImportModuleAndCreateJsAsync() function is calling SetHtml before running _initializationTcs.TrySetResult(true), and SetHtml is waiting for either the timeout or for the _initializationTcs task to complete.

I'm not sure if this is a final fix or not, it could affect other things, but I figured I would let you know what I did to fix it.

Thanks for your fast answer. The fix worked for me too.

I have the same issue, but with .NET 9, will try with the suggested fix.

I've applied the suggested fix and it is working well for me so far with no other ill effects noticed yet.

I also had to fix it using your method.
