Issue
In the[ line 88 of IconManagementContent/iconUser/Screen1.ui.qml|https://git.qt.io/mikio_hirai/shapepath_fillcolor_2dview_issue/-/blob/master/IconManagementContent/iconUser/Screen1.ui.qml?ref_type=heads#L88], ShapePath::fillColor is set to red, however, this doesn't reflectd in 2D view; instead, the icon's color is rendered as yellow. Reloading the qml file or opening another qml file and open this file again didn't resolve the issue.

<2D View>

<Live Preview>
In Live Preview, the icon color of the bottom right icon is rendered properly as red.
