Bug Report: UI Lockup on Message Interaction

Installation Method

Method used: Manual for Win10

Environment

Open WebUI Version: v0.3.28
Ollama Version: v0.3.11
Operating System: Windows 10
Browser: Version 129.0.6668.71 (Official Build) (64-bit) , also tried on Edge with same behaviour.

Confirmation:

I have read and followed all instructions provided in the README.md.
I am on the latest version of both Open WebUI and Ollama.
I have included the browser console logs.
I have provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Expected Behavior

The chat message should be clickable, allowing interaction without causing the browser to freeze or CPU to spike.

Actual Behavior

When clicking on a specific message (ID: 6fee83cf-52c6-4c20-bc44-390858f2e848), the UI freezes, and the CPU usage spikes to 100%. The browser becomes unresponsive until manually stopped.

Description

Bug Summary:
The UI becomes unresponsive when clicking on the last message (6fee83cf-52c6-4c20-bc44-390858f2e848) in the chat history, causing a CPU spike and browser freeze. (Multi-Model Messaging used)

Reproduction Details

Steps to Reproduce:

Load the attached chat history (file: chat-export-1727554950475.json). (not sure if possible via json, but found no other way)
Attempt to click on the message with ID: 6fee83cf-52c6-4c20-bc44-390858f2e848.
Observe the UI freezing and Chrome’s CPU usage spiking to 100%.

Logs and Screenshots

Browser Console Logs:

Message ID: 6fee83cf-52c6-4c20-bc44-390858f2e848
Stack Trace:
ye (MultiResponseMessages.svelte:191)
c (MultiResponseMessages.svelte:199)

Screenshots/Screen Recordings (if applicable):
[Attach screenshots or screen recordings if available]

Additional Information

This issue seems to be linked to the following snippet in the Svelte component:

<div
   class="snap-center w-full max-w-full m-1 border {history.messages[messageId]
       ?.modelIdx == modelIdx
       ? `border-gray-100 dark:border-gray-800 border-[1.5px] ${$mobile ? 'min-w-full' : 'min-w-[32rem]'}`
       : `border-gray-50 dark:border-gray-850 border-dashed ${$mobile ? 'min-w-full' : 'min-w-80'}`
   } transition-all p-5 rounded-2xl"
   on:click={() => {
       if (messageId != _messageId) {
           let messageChildrenIds = history.messages[_messageId].childrenIds;
           while (messageChildrenIds.length !== 0) {
               messageId = messageChildrenIds.at(-1);
               messageChildrenIds = history.messages[_messageId].childrenIds;
           }
           history.currentId = _messageId;
           dispatch('change');
       }
   }}

The issue could relate to the logic in on:click that handles messageChildrenIds, possibly creating an infinite loop or resource lockup.

Note

Please ensure that the bug report follows the guidelines, including all required details, logs, and reproduction steps. Thank you!
