Description:
Richt-clicking of style previews in the tabbed UI was implemented for Bug 137121.
However, when using GTK3, right-clicking the first row of styles does not open a context menu, and right-clicking the following rows of headings result in what would happen if you right-clicked somewhere in the document.

Steps to Reproduce:
1. Open Writer
2. Change "View > User Interface..." to "Tabbed"
3. Right-click on a style in the Home tab's style preview area

Actual Results:
Right-clicking the first row of styles does not open a context menu, and right-clicking the following rows of headings result in what would happen if you right-clicked somewhere in the document.

Expected Results:
Right-clicking a style preview should open a context menu.


Reproducible: Always

Using SAL_USE_VCLPLUGIN=gen will allow right-clicking as expected.
I am not sure if it ever worked with GTK3, or if it is a regression.
Jim Raykowski seems to think it is a regression: https://bugs.documentfoundation.org/show_bug.cgi?id=137121#c14
