Issue Summary

Using the Web Item module https://developer.atlassian.com/cloud/jira/platform/modules/web-item/, with information of icons, are appearing in a rectangular form for some third party apps where as the native icons do appear in a square format on the confluence system content bar.

One example for the icon code would be:

"icon": {
"width": 20,
"height": 20,
"url": "/resources/icon.png"
} 

Steps to Reproduce

1. Have a Connect app that uses the Web Item module.
2. Go to a Confluence page, having the app installed.
3. Move the mouse over the icon of the app, and it has a rectangular form instead of the square one.

Expected Results

Square format for the icon.

Actual Results

Rectangular format for the icon

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
