In Draw.Io, is there a way to copy-paste information from a drawing on one tab to a drawing in a different tab?
I couldn't find a way to do it.
Select all, copy on origin ( using keyboard ), paste using keyboard into targer. If it doesn't work, bugs go to https://github.com/jgraph/drawio/issues
I was able to do this using the scratchpad feature on the left-side menu. In the 'source' diagram, I dragged the component I wanted to copy into the scratchpad, then I opened the 'target' diagram and dragged it out of the scratchpad.
As of 11 November 2020, I have found the following solution.
Software used: Diagrams.net 13.7.9
Solution Summary: Using mouse controls to select, copy, from source drawing and paste into new drawing does not function properly. However, using keyboard controls does function correctly.
Solution Steps:

It came as a new layer 'Background' although I already had one with the same name. Hope this helps.
