I wanted to inquire if anybody else encountered the same issue as me with the CSS Editor node:
When adding the node to a workflow, I can configure it as I want, and most notably, the CTRL+Space and the Return key work perfectly. But as soon as I close the configuration dialog, some functionalities disappear. If I just close and reopen it (without executing), the CTRL+Space functionality is gone. If I in addition execute the node, I am even unable to press return to add a new line (though I can still type in text).
So my question: Is it a bug or is it just my computer who is behaving weird?
Btw: restarting KNIME helps. But only to configure the node once, then the same issue reappears.
