qmllint does not complain about invalid import URL

When I try to import an invalid import URL, qmllint does not complain.

For example:

import "¯\(ツ)/¯:/invalid/url" 

leads (only!) to the warning

Info: /Users/sami/tmp/untitled27/Main.qml:2:1: Unused import [unused-imports]
import "¯\(ツ)/¯:/invalid/url"
^^^^^^ 

My guess would be that QQmlJSImportVisitor::visit(QQmlJS::AST::UiImport *import) does not do check the URL for validity
