These two commits made the drawing of the cursor incomprehensible,
but their purpose was to fix the problem of abnormal cursor drawing
when QScriptAnalysis::Object is present. Because objects require
some special handling, they can be specially aligned or floated.

Anyway, the alignment is already reflected by ascent and descent,
and when drawing, y = position.y() + (sl.y + sl.base() - base).toReal();
works fine. So roll them back now.

We just need to specially consider the case where the QScriptItem is a
QScriptAnalysis::Object, keeping the base and descent the same as the row.
