Context

A typical programmers action is to open a WF in one WS and switching WS in order to have a look to other workflows.

Issue

When switching back to the previous WS and the already opened first WF it is not possible to connect variables anymore.
It seems that the switch back to the previous WS was not registered by the already opened WF.
The modeller does not offer the trash symbol or "+" symbol to connect any variables.

The only workaround is to close the first WF and re-open it again.

Expectation

Previously opened WFs should register the WS change back in order to offer connection lines again.
