If this issue only occurs in one browser, which browser is a problem?

Describe the Bug

When I'm using Astro Actions with more than 3 fields with errors (Validation Errors, or regular Errors) the url-encoded cookie becomes way to big to store and exceeds the 4096 character limit.

Which then it returns undefined and does not return anything on the original form

I'm also getting the strange "deleted" cookies that issue #11675 is getting.

What's the expected result?

To my understanding, the client should be correctly redirected to the original page with the correct error message.
