[Bug] Ctrl+C unable to interrupt long-running Bash commands

Bug Description
I am continually upset by regressions in claude code.

for the last week I have not been able to cancel long running Bash commands at least 10x or more.

i've tried vim mode, non vim mode...

control c will only tell me to press it again to exit. escape key only shows rewind view. control-b does not even send it to the background.
