Prerequisites

• [x ] Changes have been tested on TYPO3 v12.4 LTS
• [x ] Changes have been tested on PHP 8.2

Description

The layout used the colPos of the Contentelement for each Container. If you used a 75/25 container and placed a 50/50 container inside the 75% column, the images are calculated with multiplier 0.75 * 0.75 for the left image and 0.25 * 0.25 for the right image.

Instead of this, the colPos of the container has to be respected in calculation. And that´s what this Fix does.

Steps to Validate

1. place a 75/25 Container somwhere on the page
2. place a 50/50 container inside the 75% column of the previous container
3. place TextMedia-Elements with images inside both columns of the 50/50 container

The right image will be blurry, because the 0.25 multiplier of the outer container is also used for calculating the 50/50 container.

After this fix, both images are calculated the right way and both are the same size.
