Web engine must not send SemanticsAction during Frame #162472
Description
SemanticsActions (like pointer and key events) should only be dispatched between frames. The engine should not synchronously dispatch events while the framework is sending a semantics update to the engine.
In the strack trace below, invokeOnSemanticsAction must not be synchronously invoked from inside sendSemanticsUpdate.
When the exception was thrown, this was the stack:
