If you double-click a project symbol declaration, the symbol editor
opens. I found that I was double-clicking on the comment field and
typing with the expectation that the comment would be updated, but
it was actually setting the initial focus to the label field.
With this change the symbol editor will focus the label, value, or
comment field based on which column was double-clicked.
The behavior for Actions > Edit Project Symbol and other paths to the
symbol editor are unchanged.
Also, disabled a wayward assert.
