VST3 plugin editor resizing glitch/issues

[kunz]

I can also confirm. Same happens on linux with resizable VST3 plugins:

Linux VST3: Resize / host window does not change the size

The hosts plugin window does not change the size, when resizing VST3 plugins in Bitwig on Linux. Closing and reopen the plugin UI opens the window with the right size. Latest JUCE 6 develop branch.

Looks like the host gets no notification when the window size changes.
