"1 frame hidden (try 'help hidden_frames')" not suppressed by hf_unhide

[kalen-sj]

Once upon a time, I could type 'hf_unhide' to make the following hidden frame warning go away.

1 frame hidden (try 'help hidden_frames')

Nowadays, (ipython 8,11.0, pdbpp 0.10.3 and some versions before) this warning appears incessantly; the hf_unhide command is unheeded.

I use breakpoint() to drop into the debugger prompt.
