Does a SendMessage call bypass any other messages which have been

AFAIK, Yes. (i.e. in non-Windows LCLWidgetType implementations that
provide their own queues, SendMessage() and the main thread loop taking
an Event from the queue (can) result in the same function call to
Dispatch.)
Another reason: what when the event handler sends another message, e.g.
for reading or writing a property? Queuing the new message would result
in an deadlock.
