Description

Bug: Sidebar buttons pushed off-screen due to Flexbox overflow

Description

When generating long code blocks without line breaks, the sidebar input buttons (like "Enter") gradually move right until they're off-screen. This happens because:

1. Flex containers lack min-width: 0
2. Code blocks don't have max-width: 100% + word-break: break-all

Expected Behavior

Buttons should remain visible regardless of content length.

Workaround

Manually adding these CSS rules to ./assets/index.css fixes it:

.flex, [class*="flex"] { min-width: 0 !important; }
pre, code { max-width: 100% !important; word-break: break-all !important; }

Suggested Fix

Add to global CSS:

.container, .chat-container {
  min-width: 0;
  overflow-x: hidden;
}

Hi, I can take this up if it is still available. I’ll start by reproducing the sidebar overflow in the VS Code webview, then send a focused PR around the flex/min-width/overflow behavior with manual verification notes. Could this be assigned to me?
