explorer perspective button keeps focus

the explorer perspective button keeps focus so keyboard shortcuts no longer work in pipelines and workflows, things like space over a transform or z to open underlying pipeline.

@mattcasters can you please help me, with some scenarios around it and testing path if possible.
I will fix this and thoroughly test it and create a PR for it.

Start the Hop GUI. Makr sure a pipeline is already loaded from a previous session. Move your mouse over a transform icon and hit the space bar. Notice that nothing happens. You should see the output fields.
