PluginCommandStub.Commands.EditorGetRect(out Rectangle wndRect) seems to always return Rect(X=0, Y=0, Width=400, Height=300)

Describe the bug I am so far only using Jacobi.Vst.Samples.Host with https://www.reaper.fm/reaplugs/. Whenever I show any of their Editors, the returned Rect size is always 400x300.

To Reproduce Steps to reproduce the behavior:

1. Install https://www.reaper.fm/reaplugs/
2. Launch Jacobi.Vst.Samples.Host, load any of the plugins
3. Set a breakpoint at EditorFrame.ShowDialog call to PluginCommandStub.Commands.EditorGetRect
4. View the plugin's Editor

Expected behavior The plugin returns the correct Rect size. I have stepped through the code in OBS Studio and it loads the correct Rect size from all reaplugs.

Actual behavior Rect size always comes back as Rect(X=0, Y=0, Width=400, Height=300)

It returns non-400x300 rect when queried in OnLoad, which appears to be the more appropriate place to resize the control.

My guess is that this plugin just returns 400x300 as a default value until it has initialized fully. I have enhanced the Host Sample to implement a more robust Window Size handling of the plugin editor window. The EditorGetRect call after the plugin has initialize yield more sensible values. I have also forwarded the SizeWindow call on the host command stub to the EditorFrame. This would allow dynamically sizing plugin editors to adjust the containing editor window.
