fix: Memory leak in FluentOverflow

[JamesNK]

🐛 Bug Report

Updated to 4.4.1 and there is:

• A fast memory leak with FluentOverflow.
• Overflow control doesn't show [+1] etc when there is an overflow.

I double checked the overflow is the cause of the leak by testing the page with and without the overflow.

Without (memory usage stays constant):

With (fast leak to multiple gigabytes of memory):

💻 Repro or Code Sample

dotnet/aspire#2140

Run TestShop app host and then navigate to traces page.

🤔 Expected Behavior

Overflow counter is displayed and no memory leak.

😯 Current Behavior

No overflow counter and a memory leak.

Cause of this issue has been found. There is a StateHasChanged where it should not be. Will be fixed in next release

FYI I found perhaps a related issue with FluentOverflow - #1537. It's the same place where the memory leak was. I'm guessing the rerendering is what triggered the memory leak to grow so fast.
