Unable to set custom properties on master components in Figma Quick Controls template using Qt Bridge

Qt Bridge Version
 - Version: 4.5.1
 - Build date: 2024.06.26

Expected outcomes

When custom properties are set using Qt Bridge for a main component created without using Figma Quick Control Templates, the generated QML file includes the custom properties.

I would like custom properties to also be added to the QML file when they are applied to the main component of Figma Quick Control Templates.

Actual outcomes

When custom properties are set via Qt Bridge for the main component of Figma Quick Control Templates, the generated QML file does not include the custom properties.
