Dock Plugin SizePolicy Not Functioning

[ZhongYic00]

I'm building a dock plugin with customized size(90x40). As mentioned in recent dock updates, I override pluginSizePolicy to always return PluginsItemInterface::Custom. However the plugin widget is still always clipped by chance, and through output debugging/ gdb breakpoints it seems that pluginSizePolicy is not even called when determining container margins

Here's gdb screenshot, if pluginSizePolicy is called it'll qWarning something but it didn't.

Deb package version is

Is the newly updated fix not packaged into this version? Or it's my overriding problem?

Can you provide the code for the plugin?
