Android: QWindgetAction-Based Custom Context Menu Broken in 5.2RC

5.2-beta1 had an issue only with positioning of QWindgetAction-Based Custom Context Menu: (QTBUG-33588) Android: Context Menu Not Functioning.

5.2-rc1 adds more issues.

1. Start the application attached;
2. Write some words across the area;
3. Touch the words.

Expected: context menu appears right-down the touched words (in-context) with a list of suggested word and the size of the context menu wraps-around the suggested words;

Observed: context menu appears in the mid of the device screen,
the suggested words are not seen (text labels of push-buttons)
and the menu size is pre-defined and not defined by the width of the suggested words.

Yet another issue appeared when the example was
built with
QT += opengl

The QTextEdit area appeared as not editable (failed to set cursor
and write there) with errors as below:
