Focus doesn't move to GH Python when the code editor opened and even clicked

Is it only me who’s experience this?
Sometimes I double-click a Python component, click the code editor to make sure focus is moved to the editor, and then I hit Ctrl-F and type in some keyword. But these days, the focus is still on Rhino and my keywords goes to the command prompt of Rhino.

I do this so many times in my life and I’m pretty sure it used be like one click to the editor is enough to move the focus to the editor…
