Example of Variables view with invisible child rows

When expanding variables in the Variables view, the child rows are sometimes invisible (no name or value text). The name and value appear in the details pane at the bottom of the window when clicked and, if the child also has children, the arrow mark appears on the empty row (the child-of-child rows are visible in that case).

This behavior is inconsistent even when following the same steps (starting fresh and stopping at the same breakpoint and looking at same variable). When the problem occurs it is persistent. Stepping and manipulating the windows doesn't fix it.

In one case I was able to make a single invisible child (the first) become visible by clicking back and forth to the Expressions view. After more UI manipulation it eventually went invisible again and I could not reproduce the behavior.

When the problem is occurring in the variables view, it also occurs if the same variable is added to the Expressions view.

I added this information to bug 289517 but then noticed it's assigned to JDT and very old so not clear if that was an inappropriate place to report so apologize for possible dupe.
