This is an automated email summarizing recent activity on the  
developer-signals repo, which is where web developers add their support for  
web features that are not yet implemented in all major browsers.


JPEG XL and Anchor positioning continue to lead developer interest, with  
the latter seeing notable engagement from engineers at companies like  
Zywave and HelloWatt. Semantic discussions surfaced regarding Masonry ,  
where participants clarified the distinction between the popular library  
name and the proposed Grid Lanes implementation in CSS. New feedback for  
field-sizing from Odoo developers emphasized the friction caused by "hacky"  
JS workarounds for autogrowing inputs, underscoring the demand for native  
interoperability. Steady incremental activity persists for high-utility  
primitives like if() , Customizable <select> , and Speculation rules ,  
reflecting a consistent focus on reducing reliance on external scripts.
