LinterParseOnDerivedDataUpdate is currently set to false, to avoid redundant parsing/linting while we still trigger parses from Parsoid's pre-generation logic in RESTbase. Once that is disabled, LinterParseOnDerivedDataUpdate needs to be turned on to make sure lint data gets updated when pages are affected by template changes.
