nodebb-plugin-composer-default/static/lib/composer/categoryList.js

Lines 56 to 57 in e8e32c9

	$('.category-name').translateText(selectedCategory ? selectedCategory.name : '[[modules:composer.select_category]]');
	$('.category-selector').find('li[data-cid="' + postData.cid + '"]').addClass('active');

Breaking change so I'll leave this here till the appropriate time. Until then addressed here e5d6eb9
