Trying to overrgide the LayeredNavigation blocks with the below code on di.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/ObjectManager/etc/config.xsd">
<preference for="Magento\LayeredNavigation\Block\Navigation" type="Vendor\Module\Block\Navigation" />
<preference for="Magento\LayeredNavigation\Block\Navigation\State" type="Vendor\Module\Block\Navigation\State" />
<preference for="Magento\LayeredNavigation\Block\Navigation\FilterRenderer" type="Vendor\Module\Block\Navigation\FilterRenderer" />
</config>
We were able to override the methods inside State but not from Navigation or from FileRenderer. Any thoughts on this.
