Description Yuki Okada 2020-11-13 04:26:04 UTC 
Description of problem:
When disconnecting a session by exit command and clicking a Reset button in cockpit (web console) terminal, a prompt is not returned and any input cannot be entered. Attached the screencast.

Version-Release number of selected component (if applicable):
cockpit-224.2-1.el8.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Login to web console (cockpit) and click Terminal tab
2. Run "exit" command
3. Click "Reset" button

Actual results:
Prompt is not returned, and cannot enter anything

Expected results:
Prompt is returned

Additional info:
- This issue is NOT reproducible in cockpit-211.3-1.el8 (RHEL 8.2), so this could be a regression.
- This issue is also reproducible in cockpit-230-1.fc33.x86_64 (Fedora 33).

Thanks for the report! I confirm that with 2323/current master. So this is indeed a regression.
Comment 3 Matej Marušák 2020-11-19 12:30:21 UTC 
Indeed this is regression due to https://github.com/cockpit-project/cockpit/pull/12948/commits/29d74ff61e9d1661e56b18cc8ec8803b1df02de8

Looking into this.
