A 404 error is produced in dynamic-data-mapping-form-builder CSS in case of configuring Liferay with a non-ROOT context.
The 404 error is produced because CSS URL doesn't have the context prefix.

Wrong URL was added in LPS-93069 (see commit 54b9facafac8989a3307104184a982933bf5ec42 ) causing the issue in 7.2.x and master branches.
That code is being backported to 7.1.x in LPS-98514

Steps to reproduce

1. Configure Liferay with a non-ROOT context, for example: "test".
   • In order to do this, simply rename tomcat-9.x.y/webapps/ROOT and tomcat-9.x.y/conf/Catalina/localhost/ROOT.xml to test and test.xml
2. Start Liferay
3. Open the URL: http://localhost:8080/test , appending the context you have just added in previous step
4. Open browser developer tools => network
5. In the Navigation menu, go to Site => Content => Form
6. Click in [+] button in order to create a Form.
7. Check downloaded CSS:
   • Expected behavior: There aren't any 404 errors in browser developer tools
   • Wrong behavior: There is a 404 error in dynamic-data-mapping-form-builder CSS
