Look at the source code, there is an explanation for the new behaviour,
and it is related to GTK3 only. You can try to run your product with
GTK2 by setting the environment variable SWT_GTK3=0, this should fix
your problem. CTabFolder/CTabItem doesn't seems to have this issue,
maybe you can use that instead of the native control if you can't run
with GTK2.

I agree, this is an inconsistency that should be fixed.
Bye,
