📄 Description

Description

When scrolling through a conversation in widescreen mode that contains YAML code blocks, the message bubble widths change inconsistently. This creates a jarring layout shift where bubbles appear to resize as you scroll up and down.

Root Cause

The message bubble containers were using min-w-full which forces the element to be at least as wide as its parent — but in a flex context, this prevented the bubbles from shrinking below their content's intrinsic size. When a YAML (or any wide) code block renders, it pushes the bubble out, causing layout reflow on scroll.

The fix is min-w-0, which is the correct Tailwind class for flex children that need to shrink properly. Without it, flexbox children don't shrink below their content width.

Changes

ResponseMessage.svelte: replaced min-w-full with min-w-0 on the message content container and added min-w-0 to the flex wrapper
UserMessage.svelte: same fix applied to user bubble containers

Testing

Reproduced with the YAML preset from the issue:

Bubble widths remain consistent while scrolling in widescreen mode after the fix.

Fixes #5975
