I have a live component with the following LiveProps:

#[LiveProp]
public string $listIdentifier;

#[LiveProp(writable: true, onUpdated: 'onDataChanged', url: new UrlMapping(as: 's'), modifier: 'modifyQueryProp')]
public string $sort = '';

and this "modifyQueryProp" function:

public function modifyQueryProp(LiveProp $liveProp): LiveProp
{
    $urlMapping = $liveProp->url();
    if (!$urlMapping instanceof UrlMapping) {
        return $liveProp;
    }

    $alias = $this->listIdentifier . $urlMapping->as;

    return $liveProp->withUrl(new UrlMapping(as: $alias));
}

The component can appear several times on a page, but it always has an individual “listIdentifier.” To avoid collisions between the URL parameters, I always write the listIdentifier first in the "as" value, followed by the "as” value defined in LiveProp.

I have now updated from 2.24.0 to 2.29.1. Before, it had worked as desired. For example, if the listIdentifier was “foo” and I then changed the "sort" LiveProp to “bar,” the URL would contain the following: &foos=bar

Since the update, only the “as” value defined in LiveProp is now included in the URL: &s=bar

The change made in the modifier is therefore no longer effective.
