Bug 2002253 [wpt PR 56259] - Fix crash when two identical stylesheets don't produce RuleSets, a=testonly
Automatic update from web-platform-tests
Fix crash when two identical stylesheets don't produce RuleSets
This is a regression from CL:7185810: I forgot that StyleEngine::
RuleSetForSheet can return nullptr if the associated "media" attribute
doesn't match.
