Is there an existing issue for this? I have searched the existing issues Describe the bug When writing more than 32K of data to local storage, and then reading it, a circuit deadlock occurs, and all operations cease to execute on the circuit. It is unclear what is happening and a warning should instead be presented to the user. Expected Behavior Instead of freezing and a deadlock, a warning/error should be presented to the developer so they know what is occurring, and how to fix it. Steps To Reproduce Run the following reproduction: https://github.com/Mike-E-angelo/Stash/tree/master/Blazor.MessageLimit Press the first button Press the 2nd button Observe circuit deadlock Uncomment this line to fix the issue: https://github.com/Mike-E-angelo/Stash/blob/master/Blazor.MessageLimit/Program.cs#L12 Exceptions (if any) None, that's what this request is for .NET Version 10.0.301 Anything else? Thank you for all your great and amazing work on Blazor. 🙏

Motivation and goals Vague error messages at runtime are confusing and upsetting to the best developers, adding a type check and providing some more specific information will aid in tracking down specific attributes causing issues without having to comb through every component and splat in use on a page. In scope Developer splats attributes onto a component, the type of an attribute does not match: the developer should receive a
