Content

This pull request fixes autoplaying animated images only actually autoplaying in some cases as only thumbnail data would be fetched in the other cases.

It introduces a new ImageContentRenderer mode specifically for animated images with thumbnail sizing that always resolves to the actual image url just like stickers for example

The autoplaying feature was originally introduced in #6166

Motivation and context

This issue was brought up in the element-android matrix channel after release 1.4.18
