Hashtable Load Factor Too High Exception

### Description

We are getting a XamlParseException thrown very intermittently when under high loads.

The application displays multiple windows. Each window is running on a separate dispatcher thread.

Occasionally multiple windows (but not all) on separate dispatcher threads will fail at the same time after throwing a UnhandledDispatcherException "Hashtable insert failed. Load factor too high. The most common cause is multiple threads writing to the Hashtable simultaneously.".

We have very high GUI update rates; potentially 20,000 to 50,000 updates per second spread across 3 or 4 windows.

This issue has been reported by other users previously: https://github.com/dotnet/wpf/issues/4168

### Reproduction Steps

I'm still working on a reliable reproduction. This error only appears occasionally across hundreds of users.

Please let me know if you have any ideas on how to go about getting a reproduction.

### Expected behavior

Performing GUI updates in separate windows on separate dispatchers should be thread safe and not cause failures.

### Actual behavior
An exception is thrown when under high loads

```
