## Environment - **OS version:** Ubuntu 22.04 - **Browser version:** Chrome 117 - **Extension version:** 3.19 - **Last working version:** 3.18.1 ## Steps to reproduce 1. Run `npm install`. 2. Run `npm run build:dev chrome`. ## Observed behavior File dist/devenv/chrome/onpage-dialog-ui.postload.js contains the following code: ```js ;// CONCATENATED MODULE: ./src/onpage-dialog/content-ui/dialog.css?text const dialogtext_namespaceObject = "\n import API from \"!../../../node_modules/style-loader/dist/runtime/injectStylesIntoStyleTag.js\";\n import domAPI from \"!../../../node_modules/style-loader/dist/runtime/styleDomAPI.js\";\n import insertFn from \"!../../../node_modules/style-loader/dist/runtime/insertBySelector.js\";\n import setAttributes from \"!../../../node_modules/style-loader/dist/runtime/setAttributesWithoutAttributes.js\";\n import insertStyleElement from \"!../../../node_modules/style-loader/dist/runtime/insertStyleElement.js\";\n import styleTagTransformFn from \"!../../../node_modules/style-loader/dist/runtime/styleTagTransform.js\";\n import content, * as namedExport from \"!!../../../node_modules/css-loader/dist/cjs.js??ruleSet[1].rules[1].use[1]!./dialog.css?text\";\n \n \n\nvar options = {};\n\noptions.styleTagTransform = styleTagTransformFn;\noptions.setAttributes = setAttributes;\n\n options.insert = insertFn.bind(null, \"head\");\n \noptions.domAPI = domAPI;\noptions.insertStyleElement = insertStyleElement;\n\nvar update = API(content, options);\n\n\n\nexport * from \"!!../../../node_modules/css-loader/dist/cjs.js??ruleSet[1].rules[1].use[1]!./dialog.css?text\";\n export default content && content.locals ? content.locals : undefined;\n"; ``` ## Expected behavior File dist/devenv/chrome/onpage-dialog-ui.postload.js contains the following code: ```js ;// CONCATENATED MODULE: ./src/onpage-dialog/content-ui/dialog.css?text const dialogtext_namespaceObject = "/*\n * This file is part of Adblock Plus <https://adblockplus.org/>,\n * Copyright (C) 2006-present eyeo GmbH\n *\n * Adblock Plus is free software: you can redistribute it and/or modify\n * it under the terms of the GNU General Public License version 3 as\n * published by the Free Software Foundation.\n *\n * Adblock Plus is distributed in the hope that it will be useful,\n * but WITHOUT ANY WARRANTY; without even the implied warranty of\n * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Apparently, the resource query rules for CSS file imports were insufficient for inlining CSS code, thereby breaking the styles of the on-page dialog (see [internal comment](https://gitlab.com/adblockinc/ext/adblockplus/adblockplusui/-/issues/1470#note_1578706469)). ## Hints for testers Other UI pages should continue having working styles.
