They do receive mouse press events. They are consumed (ie. accepted)

Why don't they pass through the event filter as other events?
That’s the way Qt works. If a mouse or key event is ignored (rather than
accepted) then it will be passed to the filter.
It's the opposite in Qt, the event filter is tested first, and if the
filter returns true, the event will not even reach the widget.
See the reference doc:
https://doc.qt.io/qt-5/qobject.html#installEventFilter
And test this code where no text can be typed in a QtWidgets.QTextEdit
(and no mouse clicks) because an event filter filters events before the
QTextEdit receives them:
class Filter(QObject):
def eventFilter(self, target, ev):
return True
app = QApplication([])
f = Filter()
sci = QTextEdit()
sci.installEventFilter(f)
sci.show()
app.exec_()
So the events (like mouse press) sent to QsciScintilla should always go
through the event filter first, and if the filter returns true, the
QsciScintilla should not receive the event.
