IDefaultCoverageAnalyzer: should not color nested nodes of ignored concepts #1392
Description
Altough the DefaultCoverageAnalyzerBase.ignoredConcepts list is configured properly, the IDefaultCoverageAnalyzer result is still coloring nodes of ignored concepts in case they are part of a sub-AST.
Example: Ignore NumberLiteral
Current behaviour: In case you have an AST like 1 + 1 the entire PlusExpression (including its children) is colored.
Expected behaviour: Nodes of ignored concepts should be covered with the IGNORED_COLOR.
