Currently, JavaScriptSourceFrame._highlightExpression() directly modifiers DOM owned by TextViewer in order to highlight an expression that is used by the Popover. Occasionally, TextViewer may re-create DOM elements used by the highlight, leading to highlight being detached from the DOM tree. The correct approach would be for TextViewer to create and own the highlight.
