Actions logs auto-scroll/auto-expand not working

[merlinz01]

Description

It doesn't seem like the auto-scroll/auto-expand feature of the actions logs page is working as intended, even with those options checked.

If I refresh the page while it is running it will expand just one section and leave the others collapsed. Otherwise it all stays closed.

The first time it needs to auto-scroll it will but will not thereafter.

Gitea Version

1.25.0-rc1

Can you reproduce the bug on the Gitea demo site?

No (no actions runners set up)

Log Gist

No browser console logs.

Screenshots

This is if I do nothing after starting the workflow:

This is if I expand the "Set up job" section. Note the position of the scrollbar.

Git Version

2.39.5

Operating System

Debian 12

How are you running Gitea?

Binary download running as a systemd service.

Database

PostgreSQL

As a workaround, this Tampermonkey produces the desired effect, except it doesn't expand the first section:

// ==UserScript==
// @name         Gitea Actions logs scroll
// @namespace    http://tampermonkey.net/
// @version      2025-10-02
// @description  Auto-scroll to bottom of Gitea Actions logs
// @author       merlinz01
// @match        https://your.gitea.com/*
// @icon         none
// @grant        none
// ==/UserScript==

(function() {
    'use strict';

    const observer = new MutationObserver((mutations) => {
        mutations.forEach((mutation) => {
            mutation.addedNodes.forEach((node) => {
                if (node.nodeType === 1 && node.classList.contains("job-log-line")) {
                    node.style.scrollMarginBottom = '100px';
                    node.scrollIntoView({ behavior: 'smooth', block: 'end' });
                }
            });
            if (mutation.type === "attributes" && mutation.attributeName === "class") {
                const classList = mutation.target.classList;
                if (classList.contains("job-step-summary")
                 && classList.contains("step-expandable")
                 && !classList.contains("selected")
                 && !mutation.target.matches(':has(span[data-tooltip-content="success"])')) {
                    setTimeout(() => mutation.target.click(), 10);
                }
            }
        });
    });

    observer.observe(document.body, {
        childList: true,
        subtree: true,
        attributes: true,
        attributeFilter: ['class'],
    });

})();
