In WAB apps created in previous versions of WAB Developer edition that were imported into WAB Dev 1.2, the hints for query widget entries are impossible to read because the type color is the same shade of gray as the widget background:

Is there a way to change either the widget background or the type color of the hints? Note that the image shows the query widget nested inside a compound widget that also includes the custom ID widget.
When the query widget is a standalone widget (not nested with another widget), the widget background is white so that the gray type color of the hints is readable.
