REPL

What steps will reproduce the bug?

1. input node to enter REPL
2. input some text, such as ".help"
3. input ctrl-a to move cursor position to begin of ".help"
4. input ctrl-k to kill from the cursor position to end of line, in other words, the ".help" will be killed and disappeared, so that we can yank at next step
5. input ctrl-y to yank, the ".help" should be yanked and appear again. But, obviously, this did not happen.

And using the above steps in python's REPL, step 5 can work well.

How often does it reproduce? Is there a required condition?

always

What is the expected behavior?

ctrl-y can yank, just like in REPL of python.

What do you see instead?

No response
