Here’s the updated bug report with that clarification:

Subject: Sidebar Disappears After Pressing Page Up While Typing – Only Refresh Restores It

Description:
When using the web version of ChatGPT, pressing the Page Up key while typing in the input box causes the left sidebar to disappear from view. Although pressing Ctrl + Shift + S (toggle sidebar) shows that the sidebar is still present, it no longer appears within the visible browser window. The sidebar cannot be restored by using Ctrl + \ or F11. The only way to make the sidebar visible again is by refreshing the page. This issue occurs consistently on both Chrome and Edge browsers.

Environment:

  • Browser: Chrome (Version XX.X) / Edge (Version XX.X)
  • Operating System: Windows 11

Steps to Reproduce:

  1. Open the ChatGPT web app in Chrome or Edge.
  2. Start typing in the input box.
  3. While the cursor is active in the input box, press the Page Up key.
  4. The left sidebar disappears from the visible area.
  5. Press Ctrl + Shift + S to toggle the sidebar – this shows the sidebar is still active but hidden.
  6. Press Ctrl + \ or F11 to try restoring the sidebar – nothing happens.
  7. The sidebar only reappears after refreshing the page.

Expected Behavior:
Pressing Page Up while typing should not affect the visibility of the sidebar. If the sidebar disappears, toggling it with Ctrl + Shift + S or Ctrl + \ should restore it without needing to refresh the page.

I have just had the exact same problem. You provided a complete summary of everything. I am just replying to push this issue because it was really confusing for a good 15 minutes.
