[Bug] Probable memory leak

[sejerpz]

Describe the bug
In my application, jetbrains dotMemory report a leak by fluent validation. I'm not sure if FluentValidator is the only cause, but I see that it subscribes to EditContext OnValidationRequested and OnFieldChanged and it doesn't unsubscribe on component dispose.

To Reproduce
Use the application wich use fluent validation with an EditContext

Expected behavior
Expect all resources freed

Hosting Model (is this issue happening with a certain hosting model?):

• Blazor Server

Additional context
FluentValidationValidator version 2.1.0

This was causing me issues this week. To make a long story short I was holding onto an EditContext to preserve the state of specific form. When the EditForm and subsequent FluentValidationValidator were removed from the UI and a new one was put in it's place a second (or third, or fourth...) instance of the FluentValidationValidator would attach itself to my EditContext and I would end up with error message duplication on form submit.
