Can't resize iZotope Insight VST3 GUI

I notice that I can’t resize the iZotope Insight plugin in Wavelab 8.5.30…it just flashes and glitches but doesn’t get bigger. VST2 version will resize but not the VST3 version.

I can however resize the NUGEN VisLM2 VST3.

If the problem is with the iZotope Insight plugin, is there something I can tell them to change for support with Wavelab GUI resizing?

I know WL made some changes awhile back to accommodate iZotope Ozone GUI problems so I’m not sure if that is related to the resize problem or not.

I’m on OS X 10.10.3
