Blazor event handler re-rendering

[tsequeira-vhs]

I have a text box which has an oninput event attached to filter out characters that user can enter. This works completely fine when run on local machine, but causes the below issue in Azure deployed version.
When entering or deleting characters there is a lag and deleted characters reappear whereas entered ones disappear.

On debugging, I noticed that on every text change the view is re-rendered. This could be the cause for such a lag.

Is there any planned fix for this or any work around?
