[Bug]: Annoying Trace Listener popups when working with Winforms Designer

[Micha-kun]

Describe the bug 🐞

This week I tried to open some of my forms, but it surprised me that, suddenly, a lot of those screens are poping one after another, and only with debug info from ReactiveUI:

They show when form or user control is loading, and seems to ignore the "IsInDesignMode". If it was a single one I could tolerate, but I have forms that are showing HUNDREDS of popups one after another (because they are using a lot of bindings).
Anything changed in latest versions? Why I'm getting those popups? Any way to disable that? I'm going crazy with that.

PD: I'm detecting that there are more popups when a form inherits from a base form.

Thank you

Step to reproduce

1. Open a Form or User Control from a Winforms proyect in Design Mode
2. When designer is loading, ReactiveUI log is printing as a Message Box.
