Issue Summary

In edit mode, clicking in the page's left margin causes the cursor and page to move esoterically

A user would expect the cursor to be set directly to the right of the click, however the page esoterically scrolls upward and the cursor set to an undesired point. When it happens, it is disorienting and frustrating for the user. 

Demonstration:

• bug-demo-10.1.1-m01.mp4
• workaround-demo-10.1.1-m01.mp4

Confluence versions tested and affected:

• v8.5.20
• v9.2.8
• v10.1.1-m01

Browsers used for testing:

• Google Chrome 141.0.7390.123

Steps to Reproduce

1. Generate multiple paragraphs of text, enough to span double the current window size
2. Scroll to the bottom of the page
3. Click in the left margin

Expected Results

The cursor is set directly right of the click.

The page does not scroll

Actual Results

The cursor is set esoterically to a part of the page not visible

The pages scrolls to that point

Workaround

Add the following to Confluence Administration → Custom HTML → “at end of BODY”

<script>
try {
    require('confluence/api/event').bind('rte-ready', () => { 
        const iframe = document.getElementById('wysiwygTextarea_ifr');
        const contentDoc = iframe?.contentDocument;
        if (contentDoc?.body?.style) {
            contentDoc.body.style.height = 'auto';
        }
        if (contentDoc?.documentElement?.style) {
            contentDoc.documentElement.style.height = 'auto';
        }
    });
} catch (e) {
    console.error('Editor height patching error', e);
}
</script>
