PDF Properties window can be reduced stupidly small

SUMMARY
The PDF Properties dialog box does not resize nicely, for either the Properties or Fonts tabs. When the Properties tab is shown,  the window can be reduced in height to almost nothing, causing the text fields to crop the text and eventually disappear altogether. The Fonts tab will only extend the height of the font list to show around 13 fonts but will extend no more than that.

STEPS TO REPRODUCE
1. Open a PDF document in Okular.
2. Open the PDF Properties dialog.
3. Resize the window vertically with either tab showing.

OBSERVED RESULT
The height of the dialog can be reduced to almost zero, hiding the contents of the panel. The height of the font list on the Fonts tab will not grow in relation to the window height when resizing beyond around 13 fonts.

EXPECTED RESULT
The dialog should have a minimum height, and the font list should grow when the window height is increase.
