The customer reported that images in a Toolset template were rendering with a distorted 2:1 aspect ratio in Chrome. Investigation revealed that this issue was caused by Chrome's user agent stylesheet adding a contain-intrinsic-size attribute after the WordPress update to version 6.7. The problem did not occur in other browsers or on a different template.
Solution:
The developers released a hotfix for the affected plugins:
Toolset Blocks 1.6.18
Toolset Access 2.9.2
Customers were advised to update these plugins to their latest versions after creating a full backup.
