[Bug]: Switching between rich text components to fast, causes Microsoft.JSInterop.JSException

[BpKlomp]

I will try to. After this message I started. The bug is not as easy to reproduce as I thought it would be. Something to do with the way we switch between components with some delay somewhere. Should have something soon

Can I ask you to create a simple reproducible?

[BpKlomp]

I managed to track down what the issue was in my code. Though I did make a basic project to reproduce. Some stuff is probably unnecessary https://github.com/BpKlomp/RichTextEditBug/tree/main

If you run the project, you just have to switch between the two buttons a couple of times and it will happen quite consistently. The issue happens because of the extra state changes after switching. Its bad code, so maybe it's not worth fixing on your end. (index.razor line 37-40)

It usually happens to be the users code at fault :)

Yeah, I think this is not so much of a Blazorise issue. If you agree, I will close it.

[BpKlomp]

The issue still exists somewhere, but it might be Blazor itself. Just the way it is caused on my end can be fixed. There is still scenarios where this will happen to others, for legitimate reasons.

Probably for now its fine to close it and if someone has the same issue they can reopen it.

[BpKlomp]

It seems like the issue is more likely than I first thought. The specific code we had in place, just caused this relatively often. But there is more cases where this or a related error happens (System.NullReferenceException at Blazorise.Extensions.ObjectExtensions+d__1.MoveNex)

The problem appears whenever you trigger a StateHasChanged during the loading/unloading of the rich text editor. This could be in a different function running on the side to the one that you're using to switch objects.

I will try and see if we can improve it.
