[TIOCSTI] Bash w/o TIOCSTI requires 2x ENTER on insert of the row from HSTR via .bashrc defined fuction

[dvorka]

Problem description:

Because of Bash documented limitation, users must hit ENTER twice (once in HSTR, and then when row is inserted in the terminal):

• Bash's bind -x cannot call readline functions (no accept-line equivalent)
• Added clear documentation explaining this fundamental bash limitation
• Result: Two ENTER presses required (documented as expected behavior)

Is there any workaround / trick like in Zsh?
