Example project and screenshot

SUMMARY
When using a point size of less than 10, GroupBox captions are truncated. 

STEPS TO REPRODUCE
Create a QGroupBox widget with caption "GroupBox1" and a Noto Sans font with a point size of 8.

I've attached an example project exhibiting the problem.

OBSERVED RESULT
The centered GroupBox caption text is truncated at the left and right. The lower the size, the more pronounced the truncation. It seems the actual font size does not go down, only the width determined via QFontMetrics.size goes down, causing the truncation.

The attachment contains a screenshot.

EXPECTED RESULT
The caption is legible in its entirety. With the 'Fusion' and 'Windows' qt styles, it's working as expected.
