Hello Park,
I've just tested your scenario and for it works as expected. I'm attaching the example project, including the minified assemblies - Controls and Navigation (they are both less than 400KB uncompressed).
Can you please try it and modify the example, so that we can reproduce the issue?
If you have any problems regarding how to use the Assembly Minifier please ask us.
Read more about The Minifier.
Thank you.
