Buggy behavior with HP-80 y^x?

Buggy behavior with HP-80 y^x?
I've been working on an HP-80 emulator with this ROM.

It mostly works, but I found buggy behavior when I try to use y^x. Here are steps to reproduce:

1. 2 (Or any other number)
2. SAVE↑
3. yx

Normally, the display turns off, does the calculation, then turns back on.

But it seems there might be a bug here. The display turns back on *during* the calculation. You end up seeing an animation of it "thinking" with various random numbers quickly flashing before it gets the answer.

Can anyone who has an HP-80 please verify for me what you see?

Thank you,
Veniamin
