+ Web Inspector: REGRESSION(r188965): BackendDispatcher loses request ids when called re-entrantly
+ https://bugs.webkit.org/show_bug.cgi?id=148480
+
+ Reviewed by Joseph Pecoraro.
+
+ I added an assertion that m_currentRequestId is Nullopt when dispatch() is called, but this should
+ not hold if dispatching a backend command while debugger is paused. I will remove the assertion
+ and add proper scoping for all dispatch() branches.
+
+ No new tests, this wrong assert caused inspector/dom-debugger/node-removed.html to crash reliably.
+
+ * inspector/InspectorBackendDispatcher.cpp:
+ (Inspector::BackendDispatcher::dispatch): Cover each exit with an appropriate TemporaryChange scope.
