So if I type something (e.g. a=4) into the box to the right of >>> in the Pythonscript console, and press Enter, I get this:

Where the thick black vertical bar is a caret where the input focus now is -- I had to draw the caret in after the screenshot because I couldn't capture it.

But the question is, why does the input focus leave the box to the right of the >>> ?
Is it useful to do this? (I can't see any use)
It makes it really inconvenient to enter several commands at the >>> prompt, because I have to keep moving the input focus back to there to enter the next command

Does it happen for everyone, or just me?
Am I missing something?

I noticed this right after a clean fresh install of 1.5.4 under N++ 7.9.2 64-bit.
