If you copy and paste a text box in report builder, the pasted item has empty conditional formatting instead of having the same conditional formatting as the copied item.
Reported on LO 18.104.22.168 release.
Also tried wiping the user configuration but nothing changed.
I could confirm this never worked.
Tested with OpenSUSE 42.1 64bit rpm Linux, LO 22.214.171.124
Doesn't work since the beginning of Reportbuilder. So I set the version to "Inherited from OOo".
It has never been planned to work this way. So I set this as an ask for an enhancement.
