Scroll issue in IntelliJ

Hi there,

I'm facing an UI issue which makes it impossible to show more than 15 UISelectMany because the scroll gets hidden.

It only occours on Intellij, here is a sample project which has one command to list person(as UISelectMany): https://github.com/rmpestano/forge2512

Just increase the size input to see the issue.

I've also made a video showing it: https://youtu.be/kznd0wcXTek
