Minimize Reaper leaves FX sub-windows on screen

[DarkStar]

I dithered between posting here and as a Feature Request, but plumped for a Bug Report as the behaviour is inconsistent.

MeldaProduction plug-ins can spin off one or more sub-ordinate windows (Multiparameter, Modulator, Floating meters, Timegraph Settings etc).

When I close if I close the FX window then any sub-ordinate windows are closed too.

But if I minimise the DAW host, only the main FX window disappears; all of the sub-ordinate windows stay on screen. Can they be automatically minimised (and subsequently restored) too?

Vojtech indicated that's its down to the host not the plug-in to handle that.
